Description

[Technical Field]

[0001] This invention relates to an oscillation device, and more particularly to a magnetic energy modulation voltage-controlled oscillation device. [Previous Technology]

[0002] In current voltage-controlled oscillators (VCOs), the inductance value of the inductor used to generate the oscillation signal is fixed. Adjusting the inductance value requires replacing the entire inductor. For VCOs already in production, replacing components is extremely cumbersome. This is especially true when the VCO is manufactured using integrated circuit processes, where the inductor within the chip cannot be arbitrarily replaced. The entire VCO must be redesigned and manufactured for a specific inductance value, thus limiting the application range of current VCOs with fixed inductance values. [Summary of the Invention]

[0003] Therefore, the object of the present invention is to provide a magnetic energy modulation voltage-controlled oscillation device that can overcome at least one disadvantage of the prior art.

[0004] Therefore, the magnetic energy modulation voltage-controlled oscillation device of the present invention includes a power supply terminal, an oscillation signal output terminal group, a tuning inductor module, a capacitor module, and an interleaved coupling circuit.

[0005] This power supply terminal is suitable for connecting to a voltage source.

[0006] The oscillation signal output terminal group includes a first oscillation output terminal and a second oscillation output terminal, which are used to output a pair of oscillation signals.

[0007] The tuned inductor module includes a first tuned inductor unit, which includes a primary coil, a secondary coil, and an amplifier circuit. The primary coil is electrically connected between the first oscillation output terminal and the power supply terminal. The primary coil can generate a mutual inductance effect with the secondary coil. The amplifier circuit is electrically connected between the first oscillation output terminal and the secondary coil. The amplifier circuit generates a first output current for the secondary coil based on the voltage at the first oscillation output terminal. The ratio of the first output current to the voltage at the first oscillation output terminal is adjustable.

[0008] The capacitor module is electrically connected between the first oscillation output terminal and the second oscillation output terminal.

[0009] The interleaved coupling circuit is electrically connected between the first oscillation output terminal and the second oscillation output terminal.

[0010] The advantage of this invention lies in the fact that, compared to the fixed inductance value in current voltage-controlled oscillators (VCOs), the inductance value of the primary coil in the tunable inductor module of this invention can be controlled and modulated. This allows for adjustment to a predetermined inductance value according to actual needs without replacing inductor components or the entire VCO manufactured using integrated circuit processes, which is very convenient and quick. Therefore, this invention enables easy adjustment of the inductance value without the need to replace or remove the inductor, thereby increasing the application versatility of the VCO.

Implementation Method

[0011] Before describing the present invention in detail, it should be noted that in this disclosure, when two elements are described as "connected in series," "connected in series," or similar terms, it is intended only to indicate the series connection between the two elements, and does not necessarily imply that the current flowing through the two elements needs to be the same, nor does it limit whether there is an additional element coupled to the common junction between the two elements. The terms "connected in series," "coupled in series," or similar terms used in this invention should be interpreted as referring to the situation when these elements are viewed individually.

[0012] Referring to Figures 1 and 2, one embodiment of the magnetic energy modulation voltage-controlled oscillation device of the present invention includes a power supply terminal 1, an oscillation signal output terminal group 2, a tuning inductor module 3, a capacitor module 4, an interleaved coupling circuit 5, and two buffer circuits 6.

[0013] The power supply terminal 1 can be connected to a voltage source. The oscillation signal output terminal group 2 includes a first oscillation output terminal 21 and a second oscillation output terminal 22. The first oscillation output terminal 21 can output a first output signal, and the second oscillation output terminal 22 can output a second output signal. The first output signal and the second output signal can be inverted to each other, thus forming a pair of oscillation signals.

[0014] The tuning inductor module 3 includes a first tuning inductor unit 7 electrically connected to the first oscillation output terminal 21, and a second tuning inductor unit 7' electrically connected to the second oscillation output terminal 22.

[0015] The first tuning inductor unit 7 includes a primary coil 71, a secondary coil 72, an amplifier circuit 73, and a switch 74. More specifically, the primary coil 71 of the first tuning inductor unit 7 is electrically connected between the first oscillation output terminal 21 and the power supply terminal 1. The primary coil 71 of the first tuning inductor unit 7 can generate a mutual inductance effect with the secondary coil 72. The amplifier circuit 73 of the first tuning inductor unit 7 may include, but is not limited to, a current amplifier, and is electrically connected between the first oscillation output terminal 21 and the secondary coil 72. The secondary coil 72 includes a first terminal 721 and a second terminal 722.

[0016] The amplifier circuit 73 of the first tuning inductor unit 7 includes a control transistor 731 electrically connected to the first oscillation output terminal 21, a current mirror 732 electrically connected to the control transistor 731, and a current selector 733 electrically connected between the current mirror 732 and the secondary coil 72.

[0017] In the amplifier circuit 73 of the first tuning inductor unit 7, the control transistor 731 may be an NMOS thin-film transistor. The gate of the control transistor 731 is electrically connected to the first oscillation output terminal 21, the source of the control transistor 731 may be grounded, and the drain of the control transistor 731 is electrically connected to the current mirror 732. The current mirror 732 includes a master control transistor 734 electrically connected to the control transistor 731, and a plurality of mirror transistors 735 respectively electrically connected to the master control transistor 734.

[0018] The drain and gate of the master control transistor 734 of the current mirror 732 are electrically connected to the drain of the control transistor 731. The gate of the mirror emitter transistor 735 of the current mirror 732 is electrically connected to the gate of the master control transistor 734. The source of the mirror emitter transistor 735 and the source of the master control transistor 734 can be electrically connected to the same operating voltage Vs. In this embodiment, the source of the mirror emitter transistor 735 and the source of the master control transistor 734 can be electrically connected to the voltage source. Each master control transistor 734 and each mirror emitter transistor 735 is a PMOS thin-film transistor.

[0019] The current selector 733 is electrically connected to the drain of the mirror-emitting transistor 735. The control transistor 731 generates a first intermediate current based on the voltage at the first oscillation output terminal 21. The current mirror 732 generates a second intermediate current based on the first intermediate current. The second intermediate current may be the sum of the currents at the drains of the mirror-emitting transistor 735. In some embodiments, the current selector 733 may include a plurality of switches (not shown), each of which is electrically connected to the mirror-emitting transistor 735. In this embodiment, each of the switches is electrically connected to the drain of the corresponding mirror-emitting transistor 735, and each of the switches may be, but is not limited to, a transistor electrically connected to an operating voltage Vs. When at least one of the switches is turned on, at least a portion of the second intermediate current can flow out as a first output current.

[0020] Accordingly, the control transistor 731 of the amplifier circuit 73 can generate the first intermediate current based on the voltage at the first oscillation output terminal 21, and this current flows into the current mirror 732 to generate the second intermediate current. Furthermore, by turning on a predetermined number of the switches of the current selector 733, a predetermined portion of the second intermediate current can be controlled as the first output current. Therefore, the amplifier circuit 73 can generate the first output current for the secondary coil 72 based on the voltage at the first oscillation output terminal 21, and the ratio of the first output current to the voltage at the first oscillation output terminal 21 is adjustable.

[0021] In the first tuning inductor unit 7, since the primary coil 71 and the secondary coil 72 can generate a mutual inductance effect, and the value of the first output current input to the secondary coil 72 can be adjusted by the current selector 733, the inductance value of the primary coil 71 can be adjusted accordingly.

[0022] In other embodiments, the amplifier circuit 73 can also be designed in different circuit forms according to actual needs, as long as the second intermediate current is greater than the first intermediate current.

[0023] The first tuning inductor unit 7 is electrically connected between the secondary coil 72 and the current selector 733 of the amplifier circuit 73. More specifically, the switch 74 is electrically connected to the first end 721 and the second end 722 of the secondary coil 72 and the current selector 733 of the amplifier circuit 73.

[0024] The switch 74 includes a first switch 741 and a second switch 742. The first switch 741 is electrically connected between the first terminal 721 of the secondary coil 72 and the current selector 733 of the amplifier circuit 73. The second switch 742 is electrically connected between the second terminal 722 of the secondary coil 72 and the current selector 733 of the amplifier circuit 73.

[0025] In this embodiment, the switch 74 further includes a first transistor M1, a second transistor M2 that can serve as the first switch 741, a third transistor M3 that can serve as the second switch 742, and a fourth transistor M4. Each of the first transistor M1, the second transistor M2, the third transistor M3, and the fourth transistor M4 can be an NMOS thin-film transistor.

[0026] The first transistor M1 includes a drain electrically connected to the second terminal 722 of the secondary coil 72, a gate electrically connected to a first control voltage source Vcont1, and a groundable source. The second transistor M2 includes a drain electrically connected to the current selector 733, a gate electrically connected to the first control voltage source Vcont1, and a source electrically connected to the first terminal 721. The third transistor M3 includes a drain electrically connected to the current selector 733, a gate electrically connected to a second control voltage source Vcont2, and a source electrically connected to the second terminal 722. The fourth transistor M4 includes a drain electrically connected to the first terminal 721, a gate electrically connected to the second control voltage source Vcont2, and a groundable fourth source. Therefore, the first switch 741 is electrically connected between the first end 721 of the secondary coil 72 and the amplifier circuit 73, and the second switch 742 is electrically connected between the second end 722 of the secondary coil 72 and the amplifier circuit 73.

[0027] When the first control voltage source Vcont1 provides a high voltage (i.e., the voltage signal is "high") and the second control voltage source Vcont2 provides a low voltage (i.e., the voltage signal is "low"), the first transistor M1 and the second transistor M2 are turned on, and the third transistor M3 and the fourth transistor M4 are turned off. At this time, the first output current from the current selector 733 flows into the secondary coil 72 through the second transistor M2 and the first terminal 721, and flows out from the secondary coil 72 through the second terminal 722 and the first transistor M1.

[0028] When the second control voltage source Vcont2 provides a high voltage and the first control voltage source Vcont1 provides a low voltage, the third transistor M3 and the fourth transistor M4 are turned on, and the first transistor M1 and the second transistor M2 are turned off. At this time, the first output current from the current selector 733 flows into the secondary coil 72 through the third transistor M3 and the second terminal 722, and flows out from the secondary coil 72 through the first terminal 721 and the fourth transistor M4.

[0029] Therefore, by controlling one of the first control voltage source Vcont1 and the second control voltage source Vcont2 to provide a high voltage, and the other to provide a low voltage, ground, or negative voltage, the direction of current flow from the amplifier circuit 73 into the secondary coil 72 can be switched. In this way, the switch 74 can transfer the first output current to one of a selected first terminal 721 and a second terminal 722 of the secondary coil 72, thereby switching the direction of current flow from the amplifier circuit 73 into the secondary coil 72. In this embodiment, the high voltage is when the bias voltage is "High" (1.8V) for conduction, and the low voltage is when the applied bias voltage is "Low" (0V) for non-conduction.

[0030] The second tuning inductor unit 7' located on the left side of Figure 1 has a similar structure to the first tuning inductor unit 7 located on the right side of Figure 1. The second tuning inductor unit also includes a primary coil 71', a secondary coil 72', an amplifier circuit 73', and a switch 74'. The similarities between the second tuning inductor unit 7' and the first tuning inductor unit 7 will not be repeated here. The difference between the second tuning inductor unit 7' and the first tuning inductor unit 7 is that the primary coil 71 of the second tuning inductor unit 7' is electrically connected between the second oscillation output terminal 22 and the power supply terminal 1. The gate of the control transistor 731' of the amplifier circuit 73' of the second tuning inductor unit 7' is electrically connected between the second oscillation output terminal 22 and the secondary coil 72'. The current selector 733' is electrically connected to the drain of the mirror transistor 735' of the current mirror 732'.

[0031] In the second level-adjusting inductor unit 7', the control transistor 731' of the amplifier circuit 73 can generate the first intermediate current based on the voltage at the second oscillation output terminal 22. The current mirror 732 can generate the second intermediate current based on the first intermediate current. The second intermediate current can be the sum of the drain currents of the mirror transistor 735'. When at least one of the switches controlling the current selector 733' is turned on, at least a portion of the second intermediate current can flow out as a second output current.

[0032] Accordingly, the amplifier circuit 73' of the second tuning inductor unit 7' can generate the second output current based on the voltage on the second oscillation output terminal 22, and the output current flows into the secondary coil 72'. Furthermore, by turning on a predetermined number of the switches of the current selector 733', a predetermined portion of the second intermediate current can be controlled as the second output current, so that the ratio of the second output current to the voltage on the second oscillation output terminal 22 is adjustable.

[0033] In the second tuning inductor unit 7', since the primary coil 71' and the secondary coil 72' can generate a mutual inductance effect, and the value of the second output current input to the secondary coil 72' can be adjusted by the current selector 733', the inductance value of the primary coil 71' of the second tuning inductor unit 7' can be adjusted accordingly.

[0034] The capacitor module 4 is electrically connected between the first oscillation output terminal 21 and the second oscillation output terminal 22, and includes two capacitors 41 connected in series between the first oscillation output terminal 21 and the second oscillation output terminal. Each capacitor 41 is a variable capacitor, and a common contact of the capacitors 41 receives a control voltage Vt.

[0035] When the control voltage Vt provides each of the capacitors 41 with a predetermined amount of electrical energy, the capacitor 41 generates a predetermined capacitance. In this embodiment, the variable capacitor is a capacitor diode.

[0036] In some embodiments, one of the capacitors 41 is a variable capacitor. In some embodiments, the number of capacitors 41 may be one or more. In some embodiments, one or more of the capacitors 41 may be variable capacitors.

[0037] When the control voltage Vt is adjusted, the bias voltage of the varactor diode can be controlled to achieve different capacitance values. In this embodiment, the control voltage Vt can be a DC voltage source with a fixed voltage. It should be noted that if the capacitor 41 is a general fixed capacitor 41, the connection of the control voltage Vt can be omitted.

[0038] The cross-coupling circuit 5 is electrically connected between the first oscillation output terminal 21 and the second oscillation output terminal 22, and includes a first cross-coupling transistor T1 and a second cross-coupling transistor T2 that are cross-coupling with each other.

[0039] The first interleaved transistor T1 includes a first drain terminal T11 electrically connected to the first oscillation output terminal 21, a first gate terminal T12 electrically connected to the second oscillation output terminal 22, and a groundable first source terminal T13. The second interleaved transistor T2 includes a second drain terminal T21 electrically connected to the second oscillation output terminal 22, a second gate terminal T22 electrically connected to the first oscillation output terminal 21, and a groundable second source terminal T23. Each of the first interleaved transistor T1 and the second interleaved transistor T2 is an NMOS thin-film transistor.

[0040] In some embodiments, the first interleaved transistor T1 and the second interleaved transistor T2 may be PMOS thin-film transistors. In some embodiments, the first source terminal T13 and the second source terminal T23 may be electrically connected to other circuits.

[0041] The buffer circuit 6 is electrically connected to the first oscillation output terminal 21 and the second oscillation output terminal 22, respectively. The buffer circuit 6 can enhance the driving capability of the signal or maintain the stability of the oscillation signal, thereby improving the overall reliability of the device. In this embodiment, the buffer circuit 6 located on the right side includes a transistor 61, an inductor 62, a capacitor 63, and an impedance matching 64. The gate of the transistor 61 is electrically connected to the first oscillation output terminal 21, the inductor 62 is electrically connected between the drain of the transistor 61 and a working voltage Vs, the capacitor 61 is electrically connected between the drain of the transistor 61 and the impedance matching 64, and the source of the transistor 61 and the impedance matching 64 can be grounded. The buffer circuit 6 located on the left side is similar to the buffer circuit 6 located on the right side, except that the gate of the transistor 61 is electrically connected to the second oscillation output terminal 22.

[0042] When using this magnetic energy modulation voltage-controlled oscillator, a voltage source Vdd with a predetermined voltage is connected from the power supply terminal 1. The voltage of the first output signal of the first oscillation output terminal 21 is used as the gate voltage of the main control transistor 734 of the amplifier circuit 73 of the first tuning inductor unit 7, and the voltage of the second output signal of the second oscillation output terminal 22 is used as the gate voltage of the main control transistor 734' of the amplifier circuit 73' of the second tuning inductor unit 7'.

[0043] For the first tuning inductor unit 7, the electrical energy from the power supply terminal 1 first enters the primary coil 71, and then is transmitted through the primary coil 71 to the gate of the control transistor 731 of the amplifier circuit 73, generating the first intermediate current; then, it is converted into a second intermediate current by the current mirror 732 of the amplifier, and a predetermined portion of the second intermediate current is used as the first output current by the current selector 733. The first output current flows into the secondary coil 72 from the selected first terminal 721 or second terminal 722 of the secondary coil 72 through the switch 74, so that the primary coil 71 can generate a predetermined inductance value by utilizing the mutual inductance effect. Similarly, the second tuning inductor unit 7' can also make the primary coil 71' generate a corresponding predetermined inductance value. In this way, the magnetic energy modulation voltage-controlled oscillator can modulate the inductance values ​​of the primary coils 71, 71' of each of the first tuning inductor unit 7 and the second tuning inductor unit 7' without replacing the inductors. Therefore, the present invention can use a magnetic energy modulation voltage-controlled oscillation device of the same specification to modulate the inductance value, and can be applied to a variety of practical needs.

[0044] Furthermore, by utilizing the switch 74 of the first tuning inductor unit 7 and the design of the second tuning inductor unit 7', the current flow direction flowing into the secondary coil 72 of the first tuning inductor unit 7 and the current flow direction flowing into the secondary coil 72' of the second tuning inductor unit 7' can be changed respectively. Therefore, the primary coils 71 and 71' can have a wider range of inductance values.

[0045] Since the first or second output current injected into the secondary coils 72 and 72' via the amplifier circuits 73 and 73' can be modulated, the equivalent magnetic energy in the primary coils 71 and 71' can be changed, thereby changing the equivalent inductance of the primary coils 71 and 71' and achieving a wide-band tuning effect. Furthermore, in order to expand more energy tuning, the switch 74 and 74' can be electrically connected between the secondary coils 72 and 72' and the amplifier circuits 73 and 73' to change the direction of the first output current (or the second output current) and achieve a larger frequency tuning range.

[0046] In this embodiment, the channel width ratio of the mirror-emitting transistors 735 and 735' can be 1:2:4. For example, in the first tuning inductor unit 7, the width ratio of the main control transistor 734, the width of the first mirror-emitting transistor 735, the width of the second mirror-emitting transistor 735, and the width of the second mirror-emitting transistor 735 is 1:1:2:4. In this case, if the first output current is required to be 7 times the first intermediate current, the switches of the current selector 733 corresponding to the first mirror-emitting transistor 735, the second mirror-emitting transistor 735, and the second mirror-emitting transistor 735 can be turned on to obtain 7 times the current.

[0047] [Test Results]

[0048] Referring to Figures 1, 3, and 4, the simulated test relationship between the first output current flowing into the secondary coil 72 from the switch 74 of the first tuning inductor unit 7 and the inductance value of the primary coil 71 shows that since the current value can range from approximately -4mA to nearly 2mA, an inductance value of 2nH to 6nH can be obtained. The primary coil 71 and the secondary coil 72 can be configured to be spaced vertically (e.g., in an integrated circuit, they can be located on the 5th and 6th metal layers, respectively). The primary coil 71 is configured to include five similar and electrically connected octagonal metal layers 711 with the same center, forming a spiral shape. The secondary coil 72 is configured to include five similar and electrically connected octagonal metal layers 723 with the same center, forming a spiral shape. The two endpoints of the primary coil 71 are on the same side relative to its center (both located in the upper left of Figure 4), and the two endpoints of the secondary coil 72 are on the same side relative to its center (both located in the lower right of Figure 4). The two ends of the primary coil 71 are connected to the power supply terminal 1 and the first oscillation output terminal 21, respectively. The two ends of the secondary coil 72 are the first end 721 and the second end 722, respectively. Each octagonal metal layer 711 and 723 may have a notch and connect to the adjacent octagon. The linewidth of each octagonal metal layer 711 and 723 is 3 μm, and the spacing between adjacent octagonal metal layers 711 and 723 is 3 μm. The inner diameter of the octagonal metal layer 711 and 723 closest to the center is 146 μm.

[0049] Therefore, the test results show that, compared with the prior art, the inductance value of the primary coil 71 of the tuned inductor module 3 can not only be adjusted according to the first output current, but also effectively expand the range of inductance value adjustment by controlling the current flow direction of the first output current, and can indeed obtain a wider range of inductance values.

[0050] In summary, the magnetic energy modulation voltage-controlled oscillation device of the present invention utilizes the design of the tuning inductor module 3 to modulate the first output current flowing into the secondary coil 72 of the first tuning inductor unit 7 and the second output current flowing into the secondary coil 72' of the second tuning inductor unit 7' to be consistent, thereby adjusting the equivalent magnetic energy of the primary coil 71 of the first tuning inductor unit 7 and / or the primary coil 71' of the second tuning inductor unit 7', and further changing the equivalent inductance value of the primary coil 71 of the first tuning inductor unit 7 and / or the primary coil 71' of the second tuning inductor unit 7', so as to achieve the effect of expanding the frequency tuning range. Secondly, by utilizing the design of each of the aforementioned switches 74 and 74' (Coil Switch), the direction of the first output current and the second output current can be adjusted to increase the amount of current change, thereby increasing the tuning range of the inductance value of the primary coils 71 and 71', so that the magnetic energy modulation voltage-controlled oscillator can have a wider VCO frequency tuning range, thus achieving the purpose of the present invention.
