The technical field to which the invention relates

The present invention relates to a coil of variable inductance in the integrated design, the value of inductance which can be switched between two or more values. In one embodiment, the application of the coil of variable inductance in integrated circuits used in this type of voltage-controlled oscillator (VCO), which can be used in multi-band transceiver station (e.g., wireless communications devices, such as mobile phones, pagers, laptops, personal digital assistants (PDAs) and the like). In other embodiments, application of the variable inductance coil in the integrated design can be used in load tunable amplifier, network negotiation, full of resistance, the generator with digital control or frequency-selective inductive-capacitive network.

The level of technology

Figure 1 (prior art) shows a block diagram illustrating the main components of the traditional multi-band transceiver station 100 with direct frequency conversion (e.g., wireless communication device 100). The depicted multi-band transceiver station 100 includes an antenna 102, block 104 transmit/receive (T/R), when the intelligent tract 106, the transmit path 108 and the block 110, the signal processing of the main range. The receive path 106 includes a frequency Converter 112, which is used in conjunction with a voltage controlled oscillator 114 (VCO) to reduce radio frequency signal received by antenna 102 to a lower frequency suitable for further signal processing in block 110, the signal processing of the main range. The transmit path 108 includes a frequency Converter 116, which is used in conjunction with a voltage controlled oscillator 118 (VCO), for increasing the frequency of the signal of the main range, taken from block 110, the signal processing of the main range to a higher frequency before transmission via the antenna 102. Because radio frequency (fRF) the received signal and the transmitted signal can vary in a very wide range (more than double), multi-band transceiver 100 is required to voltage controlled oscillators 114 and 118 (VCO) had the opportunity to rebuild on a wide frequency range.

In the past for multi-band transceiver station 100 used this type of structure. In spite of this currently requires the solution of a combined transceiver station that is able to cover a wider frequency range, to support a larger share of the VA structures, multi-band and multi-standard transceiver station. These advanced features have had difficulties in implementation due to the fact that depicted in figure 1 voltage controlled oscillators 114 and 118 (VCO) have a limited range of adjustment. Provided below is the explanation, and therefore the voltage controlled oscillators 114 and 118 (VCO) have a limited tuning range.

Voltage controlled oscillators 114 and 118 (VCO) have a generation frequency (f0determined by the circuit 120 inductive-capacitive resonator containing parallel connected to each other coil 121 constant inductance and the capacitor 123 to the variable capacitance. Generation frequency (f0) is calculated using the following equation:

Because the value of the coil 121 inductance is constant, this means that the tuning range of the circuit 120 inductive-capacitive resonator is limited to capacitance ratio, which can be obtained by adjustment of the capacitor 123 to the variable capacity (i.e. Mariconda 123 and block 123 capacitive switch). The limited tuning range of the inductive-capacitive circuit 120 is not only a problem for multi-band transceiver stations 100. This is also a problem for other types of frequency-selective inductive-capacitive circuits, which may be used, for example, in loads tunable amplifier and schema matching full resistance. Next, with reference to figure 2-5 describes many of the solutions used in the past to solve this problem.

Figure 2 (prior art) shows a block diagram of a dual voltage controlled oscillator 200 (VCO), comprising two controlled voltage generator 202a and 202b (VCO)connected to the multiplexer 204. Each of the controlled voltage generators 202a and 202b (VCO) includes a circuit 206a and 206b inductive-capacitive resonator containing parallel connected with each other, the coil 205 constant inductance and the capacitor 207 variable capacity. In this case, dual voltage controlled oscillator 200 (VCO) has a full frequency range of Voutconsisting of two sub-bands Vout1and Vout2issued using controlled voltage generators 202a and 202b (VCO). Although dual voltage controlled oscillator 200 (VCO) is relatively simple, it takes more than two times larger than the area of the silicon substrate in comparison with used to create a voltage-controlled oscillator 114 (VCO), for example, depicted in figure 1. This is undesirable.

Figure 3 (prior art) shows a block diagram of a managed on whom the custody of the generator 300 (VCO), connected to the block 302 division. Voltage controlled oscillator 300 (VCO) includes circuit 304 inductive-capacitive resonator containing parallel connected to each other coil 305 a constant inductance and the capacitor 307 variable capacity. Adding unit 302 dividing the output of voltage-controlled oscillator 300 (VCO), in which the division factor can be assigned to different integer values for different output frequency ranges, effectively reduces the range requirements on the managed realignment voltage generator 300 (VCO). The addition unit 302 of division leads to a significant increase in the current consumption, especially if the requirements for phase noise are strict. Also adding unit 302 of division increases the overall area used on the chip. In addition, the adding unit 302 of division is often difficult to generate quadrature output signals for ratios, which is not a multiple of 2. None of these characteristics are not desirable.

Figure 4 (prior art) shows a block diagram of the combined schema generation frequency with feedback used to perform fractional dividing the output signal of the voltage controlled oscillator 400 (VCO). In this circuit, the voltage controlled oscillator 400 (VCO) includes the impact of the scheme 402 inductive-capacitive resonator of this type, which contains parallel connected to each other coil 403 a constant inductance and capacitor 405 variable capacity. Also the output signal of voltage-controlled oscillator (VCO) is applied to frequency Converter 404, which mixes this signal with the signal passed through the inverter 404 and divided by an integer N in block 406 division. The disadvantages of this scheme are greater current consumption and the use of a large area on a chip than any of the previous solutions, shown in figure 2-3.

Figure 5 (prior art) shows a block diagram of the combined schema generation frequency with a direct link that are also used to perform fractional dividing the output signal of voltage-controlled oscillator 500 (VCO). In this circuit, the voltage controlled oscillator 500 (VCO) includes a circuit 502 inductive-capacitive resonator containing parallel connected to each other coil 503 constant inductance and capacitor 505 variable capacity. Also the output signal of voltage-controlled oscillator (VCO) is applied to frequency Converter 504 and block 506 division. Block 506 division functions to divide the output signal by an integer N and the further submission of the divided signal to the inverter 504. Then the frequency p is OBRAZOVATEL mixes the original signal output from the divided output signal and outputs a signal V out. This scheme has drawbacks similar to the disadvantages of the scheme with feedback shown in figure 4, namely, a greater current consumption and use more space on a chip than any of the previous solutions, shown in figure 2-3.

Therefore, there is a need for a new solution that can be used to extend the tuning range voltage controlled oscillator (VCO). This new solution should not have the aforementioned disadvantages and shortcomings associated with traditional solutions. This solution is combined coil of variable inductance in integrated circuits.

Detailed description of drawings

Figure 6 depicts a block diagram illustrating a voltage controlled oscillator 600 (VCO)that includes a diagram of the inductive-capacitive resonator 602, soderjaschegosya 604 variable inductance in integrated circuits and capacitor 606 variable capacity. Coil 604 variable inductance in the integrated design performs the following procedure unique inductive switch, which allows switching its inductance between two or more values. Resulting in a voltage controlled oscillator 600 (VCO)using a coil 604 variable inductance in integrated circuits and capacitor 606 variable capacitor has a tuning range that can be extended through the use of inductive and capacitive switching (see Equation 1). In the past such an extended tuning range was not available due to the fact that the conventional voltage controlled oscillator 114 (VCO) (for example) had the tuning range, which could be changed only with the use of capacitive switching (through a capacitor 123 variable capacity), since the coil 121 had a constant inductance (see figure 1).

Coil 604 variable inductance in integrated circuits performs a unique inductive switching by adding a secondary inductance in the area of crystal primary coil inductance (see figure 10-13). The secondary coils are not physically connected with the primary coil inductance, they are associated with the primary inductor is electromagnitism way. Also the secondary coils may be connected to each other by using different configurations/topologies, so that they can change the influence that the secondary coils are the primary inductor. In particular, they can change the configuration/topology of the secondary coils, and change the value of the total inductance provided by the primary inductor.

Adding new components, like the secondary inductors, the inductor is a challenging task due to the fact that these new features introduce new parasitic elements, which can degrade the quality factor of the inductor. To avoid this problem, the preferred implementation of the present invention uses two secondary coils L21and L22the inductance associated with the primary coil L1inductance is not physical, and the electromagnetic method (see Fig.7-8). Two secondary coils L21and L22the inductors have the same inductance, and they must have the same connection with the primary coil L1the inductance. In addition, two secondary coils L21and L22inductance must have factors to the connection with the opposite sign of the mi. Thus, the total equivalent inductance of the three United by electromagnetic means structures L1, L21and L22depends on how you connect the two secondary devices L21and L22connected with each other.

If the two secondary coils L21and L22inductance connected in series, as shown in Fig.7, the effects of the two secondary coils L21and L22inductance compensate each other due to the opposite signs of the coefficients k and-k relation. In this case, the current will not pass on the side having two secondary coils L21and L22inductance, and the inductance and the quality factor of the primary coil L1inductance will remain unaffected in accordance with the following equation:

In this case, if two secondary coils L21and L22inductance connected in parallel, as shown in Fig, the effect of compensation is absent. The total value of the inductance of the primary coil L1the inductance decreases to a new value LTHEthat depends on the magnitude of the coefficient k due, in accordance with the following equation:

In this topology, the resulting quality factor of the coil 604 variable inductance in integrated IV the Institute is also reduced due to the fact, the resistance loss is not reduced by similar values to the value of the inductance. As can be seen in Fig.7 and 8, two secondary coils L21and L22inductance is always connected to each other for forming a closed loop, and this is the only topology within this closed loop, which can be changed through the serial or parallel connection.

In a preferred embodiment, the coil L1, L21and L22inductance in integrated circuits implemented as metal tracks on top of the semiconductor substrate (crystal). All important operating parameters, similar to the value of the inductance, quality factor and electromagnetic connection with other metal structures, is determined by the geometric properties of the placement of the inductor together with the properties of the substrate material. It is also important to determine the correct size and place the metal tracks, which are used to create coils L1, L21and L22the inductance. The following is a description of some of the other accommodation options that can be used to make coils L1, L21and L22the inductance.

Figure 9 shows a block scheme is a, illustrating the accommodation of single-turn primary coil L1inductance, shaped in the form of figure 8. In this example, the primary coil L1inductance has the form of a single-turn structure shown at Fig, with the upper circuit 902 and the lower circuit 904. On the basis of the form depicted in Fig, the current in the upper loop 902 passes in the direction (for example, in a clockwise direction, see arrow)opposite to the direction of the current in the lower loop 904 (e.g., counterclockwise, see arrows). In the configuration in the form of figure 8 has the advantage that the magnetic field 906 and 908, coming from these two private circuits 902 and 904, have opposite signs. This means that the magnetic field 906 and 908, which are emitted at a certain distance from the primary coil L1inductance, tend to neutralize each other, reducing the effect of the far field, the primary coil L1inductance can have on other components (for more details of this benefit, please refer to the application for U.S. patent No. 10.919.130, pending). Another advantage of this symmetrical placement of the primary coil L1inductance is the suitability for implementing the method inductive switching this is subramania, as is discussed below.

Figure 10, which shows a block diagram of an illustrative coil 604 variable inductance in the integrated design, depicts two secondary coils L21and L22inductance associated electromagnetic method with a single-turn primary coil L1inductance, shaped in the form of figure 8, according to the present invention. Located in the center of the key 1002 remains open, resulting in a serial connection of a closed loop with two secondary coils L21and L22the inductance. For example, the key 1002 may be a software-managed large MOS transistor 1002 (MOS). The full symmetry of the placement of the coils L21and L22inductance ensures that the coupling coefficients of the secondary coils L21and L22inductance identical to each other in value. Also symmetrical in form of figures 8 primary coil L1inductance automatically ensures that the coupling coefficients of the secondary coils L21and L22inductance have opposite signs. Consequently the primary coil L1inductance has two private circuit 902 and 904 having opposing magnetic fields 906 and 908. Resulting coil 604 variable inductance in integrated design in this configuration operates is the quality of the scheme, depicted in Fig.7, and the total inductance LTOTequal to the inductance of the primary coil L1the inductance.

Figure 11 depicts a block diagram of an illustrative coil 604 variable inductance in the integrated design, depicted in figure 10, where the key 1002 is closed, therefore, the secondary coil L21and L22inductance connected in parallel. And in this case, the full symmetry of the placement of the coils L1, L21and L22inductance ensures that the coupling coefficients of the second coils L21and L22inductance identical to each other in value. The topology of the coils L1, L21and L22inductance does not change, because the secondary coil L21and L22inductance still have coupling coefficients with opposite signs. Resulting coil 604 variable inductance in integrated design in this configuration functions as the circuits shown on Fig, and the total inductance LTHEis reduced according to equation 3.

On Fig depicts a block diagram of an illustrative coil 604 variable inductance in integrated design that includes two secondary coils L21and L22inductance connected by electromagnetic means with dvuhvekovoi primary coil L1inductance,shaped in the form of figure 8, according to another variant implementation of the present invention. Dvuhmetrovaya primary coil L1inductance, shaped in the form of figure 8, is very similar to that shown in figure 10-11 single-turn primary coil L1inductance, shaped in the form of figure 8, where it includes the upper circuit 902 and the lower circuit 904. However dvuhmetrovaya primary coil L1inductance, shaped in the form of figures 8 and includes two circuits, has a lower quality factor and structurally less similar values of inductance in comparison with the single-turn primary coil L1inductance, shaped in the form of figure 8, which is shown on figure 10-11. The mechanism 1002 switch may be similar to the mechanism depicted in figure 10-11.

In both cases, the implementation coil 604 and 604' variable inductance in integrated execution should be noted that depending on the actual placement of the coils L1, L21and L22the inductance values of the inductance connected secondary coils L21and L22inductance may vary slightly between successive configuration and a parallel configuration. However, this is not a problem provided that the values of inductance equal to L21=L22between the two is topicname coils L 21and L22the inductance. Although one pair of secondary coils L21and L22inductance is depicted and described above with reference to Fig.7-12, it is also possible to carry out several pairs of secondary coils, which will provide the primary coil L1inductance is the ability to output more than two inductance values. The use of multiple pairs of secondary coils may be desirable, since the use of inductive radio buttons instead of capacitive switches for frequency tuning and probably less sensitive to variations in process parameters. The reason is that inductive switches are closely related with the configuration of the device, which can more accurately be controlled. For example, the value of k factor of communication can be managed using tools laser cutting machine for configuration changes (for example, size, shape) of the secondary coils in comparison with the primary coil L1the inductance. Tools laser cutting can also be used to replace a key 1002 MOS if desired, a single execution of the entire adjustment (trim) coil 604 variable inductance in integrated circuits during fabrication to compensate for process changes in other whom Ananth, which affect the frequency of the voltage controlled oscillator (VCO).

A large variety of configurations can be used for switchable coils 604 variable inductance in the integrated design, which carries out many pairs of secondary coils provided a simple support opposite signs for different coefficients k connection of the secondary coils. One such example is depicted in Fig, here the coil 604" variable inductance in the integrated design includes a primary coil L1inductance having the form of a clover leaf, and four secondary coils L21, L22, L23and L24the inductance. Four secondary coils L21, L22, L23and L24inductance is used for the inductive switch, where two secondary face L21and L23inductance (for example) have positive coefficients k connection, and the other two secondary coils L22and L24inductance (for example)have negative coefficients to the relationship. The mechanism 1002 switch may be similar to the mechanism depicted in figure 10-11.

As mentioned above, the coil 604, 604' and 604" variable inductance in integrated circuits can be implemented in a wide variety of devices. For example, elimination of the CTB, such loads tunable amplifier, networking, negotiation, full resistance generator with digital control or other types of frequency-selective selectable inductive-capacitive networks can benefit from the Association and the use of a wider range of adjustment coils 604, 604' and 604" variable inductance in integrated circuits. In addition, the multi-band transceiver radio 1400, similar to that shown in Fig, to gain an advantage by using two coils 604, 604' and 604" variable inductance in integrated circuits.

On Fig depicts a block diagram illustrating the main components of the multi-band transceiver radio 1400, according to the present invention. The depicted multi-band transceiver radio 1400 (for example, the device 1400 wireless) includes antenna 1402, block 1404 transmit/receive (T/R), the receive path 1406, the transmit section 1408 and block 1410 signal processing of the main range. The receive path 1406 includes a frequency Converter 1412, which is used in conjunction with a voltage controlled oscillator 1414 (VCO) to reduce radio frequency signal received through the antenna 1402, to a lesser frequency, suitable for further signal processing in block 1410 signal processing on the main range. Tract 1408 transmission includes the inverter 1416, which is used in conjunction with a voltage controlled oscillator 1418 (VCO) to increase the frequency of the signal of the main range, taken from block 1410 signal processing of the main range to a higher frequency before transmission using the antenna 1402.

Multi-band transceiver radio 1400 has the configuration similar to traditional multi-band transceiver stations 100, depicted in figure 1, except that the ranges of adjustment controlled by the voltage generator 1414 and 1418 (VCO) more ranges of managed realignment voltage generator 114 and 118 (VCO)used in traditional multi-band transceiver station 100.

In turn, voltage controlled oscillators 1414, 1418 (VCO) have extended the tuning range due to the fact that they can use a combination of inductive switching (through the coil 604, 604' and 604" variable inductance in integrated circuits and capacitive switching (through the capacitor 606 variable capacity). In the past this extended range of adjustment was not possible due to the fact that the conventional voltage controlled oscillators 114 and 118 (VCO) had the tuning range, which could be changed only when using the AI capacitive switching (through a capacitor 123 variable capacity), since it was installed coil 121 inductance (see figure 1). For clarity, described in the present document description multiband transceiver station 1400 omits some details about well-known components that are not necessary for understanding the present invention.

Another advantage associated with the use of coil 604, 604' and 604" variable inductance in integrated design in multi-band transceiver radio 1400 (or any device)is less mutual electromagnetic coupling between the controlled voltage generator 1414 and 1418 (VCO). The reason is that each coil 604, 604' and 604" variable inductance in the integrated design is symmetrical. In addition, since each coil 604, 604' and 604" variable inductance in the integrated design consists of a set of symmetric contours, this means that each of them emits a magnetic field that tends to neutralize itself. Consequently the two coils 604, 604' and 604" variable inductance in integrated circuits can be placed and oriented in some way, in which the induced current in one coil 604, 604' and 604" variable inductance in integrated circuits is significantly reduced due to magnetic the field, created by another coil 604, 604' and 604" variable inductance in integrated circuits. For a more detailed discussion of this and other advantages associated with the use of the symmetric primary coil inductance, reference is made to patent application U.S. No. 10/919,130, pending.

On Fig depicts a block diagram illustrating the main steps of a method 1500 of manufacturing coil 604, 604' and 604" variable inductance in integrated circuits according to the present invention. At step 1502 multi-circuit of the primary coil L1inductance is formed by placing the metal tracks on the crystal. At step 1504, one or more pairs of secondary coils L21and L22inductance, for example, are formed by placing a metal track marks on the crystal. As discussed above, the secondary coil L21and L22inductance is connected with a multi-circuit of the primary coil L1the inductance of the electromagnetic means. Secondary coil L21and L22inductance form a closed loop that has a variable topology, which can be switched between the serial connection and parallel connection. At step 1506 is formed on the crystal key 1002. Key 1002 is used to swap the treatment variable topology of the secondary coils L 21and L22inductance, as well as to change the value of the inductance provided by the multi-circuit of the primary coil L1the inductance.

Below are some additional features and advantages associated with the present invention.

The use of switchable inductor in the resonator voltage controlled oscillator (VCO) extends the tuning range of the frequency threshold capacitive keys. This allows you to use a single voltage controlled oscillator (VCO) to cover more bands multiband transceiver station. Furthermore, the area of the crystal combined voltage-controlled oscillator (VCO) is relatively large due to the coil inductance and reduced number of voltage-controlled oscillators (VCO), which means a significant reduction in the cost of crystal transceiver.

Switchable inductor has an inductance value that can be set to an arbitrary value (within certain thresholds) by changing the coefficient k of the connection between the windings. The stage is almost not dependent on the change process as it is defined, mainly, by means of geometrical parameters.

The secondary coils are connected with the circuits of the second resonator means, other than electroplating. This minimizes parasitic effects and facilitates key item, because you can apply the appropriate voltage to the secondary windings.

Method inductive switching can be used for a wide variety of accommodation options inductor, and its use will not occupy a much larger area of the crystal as compared with the conventional inductor.

Method inductive switching can be used as accommodation options inductors have a reduced electromagnetic coupling to other conductors located on the crystal or beyond.

The secondary coil inductance can introduce additional losses, being in parallel connection with low inductance. Therefore the quality factor of the inductor can be reduced, and may be reduced parameter phase noise voltage controlled oscillator (VCO). However, this can easily be compensated by increasing the power options applications where the requirements for phase noise are strict.

In this case, changes in the production process lead to a controlled voltage generator (VCO) (which includes a coil variable is th inductance in integrated circuits), low-frequency generation, and then to increase the oscillation frequency to an acceptable value can be performed in the industrial processing of inductors.

SUBSTANCE: in one aspect, power control (PC) is supported in several PC modes such as "up-down" PC mode and delete-based PC mode. One PC mode may be selected for use. Service signals may be sent to indicate the selected PC mode. If the "up-down" PC mode is selected, the base station assesses the quality of the received signal for the terminal and sends PC commands in order to instruct the terminal to adjust its transmission power. If the delete-based PC mode is selected, the base station sends delete indicators which indicate whether code words received from the terminal are deleted or not. In both PC modes, the terminal controls its transmission power based on a power control feedback (e.g. a PC command and/or delete indicators) in order to attain the target level of efficiency (e.g. target deleting frequency for code words). Delete indicators may also be used for handover.

EFFECT: reduced noise and achieving high efficiency for all terminals.
