Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a parameter adjustment device, method, equipment, high-frequency radio frequency system, and storage medium. Background Art

[0002] In a high-frequency radio frequency system, due to the high-frequency segment loss of the analog front end, an equalization circuit is required to compensate for the high-frequency loss; compared with digital equalization, by improving the flatness of the frequency response of the analog channel through the analog equalization method, the phenomenon of signal-to-noise ratio deterioration during the sampling process of the subsequent AD (Analog-to-Digital) can be effectively improved.

[0003] Analog equalization realizes the high-frequency warping of the frequency response curve by introducing a coupling structure between two operational amplifiers. Since it adopts the form of an external lap adjustment circuit, this method can only work at a relatively low frequency. To increase the operating frequency, an equalization circuit in the form of a current transformer equalization loop was proposed. This structure suppresses the low-frequency gain of the amplifier in the differential amplifier circuit through a degeneration loop placed between the emitters of two transistors in the differential amplifier circuit, thereby increasing the high-frequency gain. However, currently, the adjustment parameters of the current transformer equalization loop are single, and linear adjustment cannot be achieved. Summary of the Invention

[0013] In the case of adopting the above technical solution, by adjusting the resistance value of the resistive element in the first resistive element branch, the amplitude of the frequency response curve within a specific frequency range can reach the expected level, so as to realize the adjustment of the amplitude of the frequency response curve.

[0014] In a possible implementation manner, the target parameter is the amplitude of the frequency response curve, and the target adjustment circuit includes a gain adjustment circuit and an output matching adjustment circuit; the target adjustment circuit may further include at least one of an input matching adjustment circuit and a bias adjustment circuit.

Moreover, this adjustment process realizes the linear adjustment effect of the swing amplitude of the frequency response curve through the coordinated adjustment of multiple element branches in multiple adjustment circuits, improving the accuracy of the adjustment.

This adjustment process only includes the analysis of the control signal and the control of each switching device, so this control process has a relatively fast response speed, and can make the frequency response curve meet the linear adjustment requirements of the system within a short time. Moreover, this adjustment process realizes the linear adjustment effect of the extreme value amplitude of the frequency response curve through the coordinated adjustment of multiple element branches in multiple adjustment circuits, improving the accuracy of the adjustment.

[0095] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all the implementation manners consistent with this application. On the contrary, they are merely examples of devices and methods consistent with some aspects of this application as detailed in the appended claims.

[0096] Unless otherwise defined, all the technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application. It can be understood that the terms "first", "second", etc. used in this application can be used herein to describe various information or data, but these elements are not limited by these terms. These terms are only used to distinguish one piece of information from another. For example, without departing from the scope of this application, the first action information can be called the second action information, and similarly, the second action information can be called the first action information. Both the first action information and the second action information are action information, but they are not the same action information.

[0097] First, the nouns involved in this application are explained:

[0098] High-frequency radio frequency system: It refers to a wireless communication system operating in the high-frequency band.

[0099] Single-stage differential amplifier circuit: It is a basic analog circuit used to amplify the difference between two input signals while suppressing their common-mode signals.

[0100] Frequency response curve: It is a graphical representation describing the gain or response characteristics of a system at different frequencies. The frequency response curve is usually plotted with frequency on the horizontal axis and gain or amplitude on the vertical axis. By analyzing the frequency response curve, the performance of the system at different frequencies can be understood.

[0101] Linear adjustment: It means that when changing a single parameter of the frequency response curve, without changing the values of other parameters, the changing trend of the curve does not change.

[0102] Linear adjustment

[0103] The parameter adjustment device provided by the embodiments of the present application is applied to a high-frequency and high-speed radio frequency system and is used to compensate for the medium and high-frequency losses of the system. The high-frequency loss compensation of the high-frequency and high-speed radio frequency system needs to meet high-precision linear adjustment to ensure that the high-frequency loss compensation can reach the expected performance standard and avoid excessive or insufficient compensation.

[0104] Specifically, in order to reach the expected performance standard, when adjusting the amplitude, the swing and the extreme frequency remain unchanged, and the overall frequency response curve rises; when adjusting the swing, the amplitude and the extreme frequency remain unchanged, the low-frequency gain of the frequency response curve remains unchanged, and the rising amplitude of the gain changes with the frequency; when adjusting the extreme frequency, the amplitude and the extreme amplitude remain unchanged, and the extreme frequency point of the frequency response curve shifts; when adjusting the extreme amplitude, the amplitude, the swing and the extreme frequency remain unchanged, and the curves of the frequency response curve basically coincide before reaching the extreme value, and only the extreme amplitude changes. However, in the high-frequency and high-speed radio frequency system, the adjustment of peaking is limited by high-frequency parasitics and cannot be achieved by adjusting a single component value like in a low-frequency system.

[0105] In view of the above problems, the present application designs a technical solution including multiple adjustment circuits, which can adjust different parameters of the frequency response curve of the system by changing the target adjustment circuit in the multiple adjustment circuits. The adjustment parameters include but are not limited to the amplitude, swing, extreme frequency, extreme amplitude, etc. of the frequency response curve. Moreover, the present application can also achieve linear adjustment of a single parameter through the coordinated adjustment of multiple components in the multiple adjustment circuits. Among them, the linear adjustment can be high-frequency linear adjustment.

(4) Load resistors; a load resistor is connected to the collector or drain of each transistor. (5) Output terminals, and two output terminals are respectively led out from the collectors or drains of the two transistors to output differential signals.

[0113] In this differential amplifier circuit, the input matching adjustment circuit is connected to the input terminal of the single-stage differential amplifier circuit, the output matching adjustment circuit is connected to the output terminal of the single-stage differential amplifier circuit, the gain adjustment circuit is connected between the current amplification structure and the current source of the single-stage differential amplifier circuit, and the bias adjustment circuit is connected between the current amplification structure and the load resistor of the single-stage differential amplifier circuit.

[0114] In some examples, the gain adjustment circuit can be connected to the emitter of the current amplification structure of the single-stage differential amplifier circuit, and the bias adjustment circuit can be connected to the collector of the current amplification structure of the single-stage differential amplifier circuit.

[0115] In some other examples, the gain adjustment circuit can be connected to the collector of the current amplification structure of the single-stage differential amplifier circuit, and the bias adjustment circuit can be connected to the emitter of the current amplification structure of the single-stage differential amplifier circuit.

[0116] Optionally, the above input matching adjustment circuit can be used to adjust the matching impedance at the input end of the single-stage differential amplifier circuit, the output matching adjustment circuit can be used to adjust the matching impedance at the input end of the single-stage differential amplifier circuit, the gain adjustment circuit can be used to adjust the gain of the system, and by adjusting the gain, the amplification degree of the signal can be controlled. The bias adjustment circuit can be used to adjust the bias current or voltage of the current amplification structure.

[0117] Based on the above description, in the embodiment of the present application, an input matching adjustment circuit, an output matching adjustment circuit, a gain adjustment circuit, and a bias adjustment circuit are respectively introduced between the input end, the output end, the current amplification structure of the single-stage differential amplifier circuit and the current source and the load resistor. At least one of these circuits can adjust the target parameters of the frequency response curve according to the linear adjustment requirements of the frequency response curve of the system. Based on this, linear adjustment of a single parameter can be achieved. It should be understood that when the linear adjustment requirements of the frequency response curve of the system change, the corresponding target parameters to be adjusted will also change accordingly. Therefore, the present application can adjust multiple parameters of the frequency response curve.

[0118] It should be understood that for different linear adjustment requirements of the frequency response curve, different target parameters need to be adjusted to compensate for the high-frequency loss of the system.

[0119] In the embodiment of the present application, the linear adjustment requirements may include any one of changing the low-frequency gain of the frequency response curve to the target gain, changing the curve swing before the extreme frequency of the frequency response curve to the target swing, changing the extreme frequency of the frequency response curve to the target extreme frequency, and changing the extreme amplitude of the frequency response curve to the target extreme amplitude.

[0120] It should be understood that the above target gain, target swing, target extreme frequency, and target extreme amplitude can be determined according to the high-frequency loss of the system.

[0121] The target parameters of the frequency response curve may include any one of the amplitude of the frequency response curve, the swing of the frequency response curve, the extreme frequency of the frequency response curve, and the extreme amplitude of the frequency response curve.

[0122] When it is necessary to change the low-frequency gain of the frequency response curve to the target gain, the amplitude of the frequency response curve can be adjusted. At this time, the target adjustment circuit includes at least a gain adjustment circuit; the gain adjustment circuit includes a first resistive element branch, and the first resistive element branch includes a resistive element, and the resistive element is used to adjust the amplitude of the frequency response curve.

[0123] It should be understood that the impedance of the resistive element is independent of frequency, which means it has the same impedance for signals of all frequencies. The gain refers to the ratio of the output signal amplitude to the input signal amplitude, and the gain of the circuit can be controlled by adjusting the impedance of the circuit. For the frequency response curve, the change in gain will affect the amplitude response of the signal at different frequencies. Therefore, by adjusting the resistance value of the resistive element in the first resistive element branch, the amplitude within a specific frequency range of the frequency response curve can be made to reach the expected level.

[0124] When it is necessary to change the extreme frequency of the frequency response curve and swing the curve amplitude in front to the target swing amplitude, the swing amplitude of the frequency response curve can be adjusted. At this time, the target adjustment circuit at least includes a gain adjustment circuit. The gain adjustment circuit includes a fourth capacitive element branch, and the fourth capacitive element branch includes a capacitive element, and this capacitive element is used to adjust the swing amplitude of the frequency response curve.

[0125] It should be understood that a capacitive element (such as a capacitor) is used to store and release charge in the circuit and has an impedance characteristic that depends on frequency. Its impedance decreases as the frequency increases. Due to this frequency dependence, the capacitor has different effects on signals of different frequencies. The swing amplitude of the frequency response curve refers to the change in signal amplitude within a specific frequency range. Therefore, the signal amplitude can be adjusted through the capacitive element, and then the signal swing amplitude within a specific frequency range can be adjusted.

[0126] When it is necessary to change the extreme frequency of the frequency response curve to the target extreme frequency, the extreme frequency of the frequency response curve can be adjusted. At this time, the target adjustment circuit at least includes a bias adjustment circuit; the gain adjustment circuit includes a first inductive element branch, and the first inductive element branch includes an inductive element, and this inductive element is used to adjust the extreme frequency of the frequency response curve.

[0127] It should be understood that an inductive element (such as an inductor) is used to store and release magnetic energy in the circuit, and its impedance (referred to as reactance) increases as the frequency increases. Due to this frequency dependence, the inductor has different effects on signals of different frequencies. The extreme frequency usually refers to the resonant frequency of the circuit. By changing the inductance value of the inductive element, the resonant frequency can be directly affected, thereby adjusting the extreme frequency of the frequency response curve.

[0128] When it is necessary to change the extreme amplitude of the frequency response curve to the target extreme amplitude, the extreme amplitude of the frequency response curve can be adjusted. At this time, the target adjustment circuit at least includes a bias adjustment circuit; the bias adjustment circuit includes a third resistive element branch, and the third resistive element branch includes a resistive element, and this resistive element is used to adjust the extreme amplitude of the frequency response curve.

[0129] It should be understood that the extreme value amplitude refers to the maximum or minimum response amplitude of the frequency response curve at a certain frequency. By adjusting the gain in the circuit, the extreme value amplitude can be changed. The gain is usually determined by the ratio of the feedback resistor to the input resistor. By changing the values of these resistors, the gain of the circuit can be adjusted, thereby affecting the extreme value amplitude. Therefore, in this application, the extreme value amplitude of the frequency response curve can be changed through the third resistive element branch.

[0130] In one example, the resistive element of any one of the input matching adjustment circuit, the output matching adjustment circuit, the gain adjustment circuit, and the bias adjustment circuit is a variable resistor, and / or the inductive element is a variable inductor, and / or the capacitive element is a variable capacitor. Based on this, the embodiments of this application can set the element values in the corresponding adjustment circuit according to different adjustment values of the adjustment parameters to meet different adjustment requirements.

[0131] For example, when it is necessary to change the low-frequency gain of the frequency response curve to the target gain, the capacitance value of the variable capacitor in the gain adjustment circuit can be determined according to the difference between the current low-frequency gain value and the target gain value of the frequency response curve to compensate for the high-frequency loss of the system. Specifically, the capacitance value of the variable capacitor in the gain adjustment circuit can be determined by querying the preset gear configuration information table according to the difference between the current low-frequency gain value and the target gain value of the frequency response curve. Among them, the preset gear configuration information table can be set according to experience or experimental data, and the embodiments of this application do not make special limitations on this.

[0132] Another example is that when it is necessary to change the extreme value frequency of the frequency response curve to the target extreme value frequency, the inductance value of the variable inductor in the bias adjustment circuit can be determined according to the difference between the current extreme value frequency and the target extreme value frequency of the frequency response curve to compensate for the high-frequency loss of the system. Specifically, the inductance value of the variable inductor in the bias adjustment circuit can be determined by querying the preset gear configuration information table according to the difference between the current extreme value frequency and the target extreme value frequency of the frequency response curve.

[0133] As can be seen from the above, the parameter adjustment device provided by the embodiments of this application is applied to the scenario where medium and high-frequency loss compensation is required in a high-frequency and high-speed radio frequency system. In this scenario, when adjusting the target parameter, linear adjustment needs to be satisfied. Among them, linear adjustment means that when changing a single parameter of the frequency response curve, the values of other parameters remain unchanged, and the curve change trend also remains unchanged. Based on this, referring to Figure 3a , the embodiments of this application need to satisfy that when adjusting the amplitude, the swing amplitude and the extreme value frequency remain unchanged, the gain of the frequency response curve increases, and the shape of the frequency response curve remains unchanged; referring to Figure 3b , the embodiments of this application need to satisfy that when adjusting the swing amplitude, the amplitude and the extreme value frequency remain unchanged, the low-frequency gain of the frequency response curve remains unchanged, and the gain increase amplitude changes with the frequency; referring to Figure 3c, the embodiments of the present application need to meet that when adjusting the extreme frequency, the amplitude and the extreme amplitude remain unchanged, and the frequency of the extreme frequency point of the frequency response curve shifts; refer to Figure 3d , the embodiments of the present application need to meet that when adjusting the extreme amplitude, the amplitude, the swing amplitude, and the extreme frequency remain unchanged, and the curves before reaching the extreme value of the frequency response curve are basically coincident, and only the extreme amplitude changes.

[0134] It should be understood that in a high-frequency system, the adjustment of peaking is limited by high-frequency parasitics and cannot achieve linear adjustment of the peaking curve by adjusting a single component value like in a low-frequency system. However, the parameter adjustment device proposed in the embodiments of the present application can effectively solve this problem. When a signal enters the system, affected by high-frequency insertion loss (including but not limited to passive transmission loss and high-frequency gain roll-off of the active structure), the frequency response continuously decreases as the frequency increases, as shown in Figure 4 the curve 1 in. At this time, a curve with peaking in the high frequency of the frequency response curve is added to the system, as shown in Figure 4 the curve 3 in. After compensation, the high-frequency part of the system frequency response curve is raised, as shown in Figure 4 the curve 2 in. Where A0 is the target gain value after compensation, A1 is the high-frequency gain value; F1 is the 1dB bandwidth, F2 is the 3dB bandwidth; D1 is the high-frequency peaking compensation value, D2 is the high-frequency passive loss value, and D1 and D2 are equal in magnitude.

[0135] It should be noted that the above peaking may refer to the phenomenon that the gain of the system appears as a peak within a specific frequency range, and the gain of a certain frequency band in the frequency response can be increased through peaking to compensate for the attenuation of the frequency response of other parts in the high-frequency system.

[0136] Optionally, the embodiments of the present application can linearly adjust the target parameter in the following manner.

[0137] First, the structure of each adjustment circuit will be described.

[0138] Referring to Fig. 5, a structural diagram of an input matching adjustment circuit is shown. The input matching adjustment circuit includes a second capacitive element branch and a second resistive element branch; wherein, the second capacitive element branch may include a tunable capacitor C1, or a tunable capacitor C2, or a branch formed by connecting the tunable capacitors C1 and C2 in series, and the second resistive element branch may include a tunable resistor R1, or a tunable resistor R2, or a branch formed by connecting the tunable resistors R1 and R2 in series. It should be understood that Figure 5 Fig. shows a specific circuit structure of the input matching adjustment. The input matching adjustment circuit may also have other structures, and the embodiments of the present application do not make special limitations on this.

[0139] Referring to Figure 6, which shows a structural diagram of an output matching adjustment circuit. The output matching adjustment circuit includes a first capacitive element branch. Among them, the first capacitive element branch may include a branch formed by one or any two of the adjustable capacitors C3, C4, C5, and C6 connected in series. It should be understood that Figure 6 illustrates the specific circuit structure of the output matching adjustment circuit. The output matching adjustment circuit may have other structures, and the embodiments of the present application do not make special limitations on this.

[0140] Referring to Figure 7 , which shows a structural diagram of a bias adjustment circuit. The bias adjustment circuit may include a third resistive element branch, a first inductive element branch, and a third capacitive element branch. The third resistive element branch includes a branch formed by the adjustable resistor R3, or the adjustable resistor R4, or the adjustable resistor R4. The third capacitive element branch includes a branch formed by the adjustable capacitor C7. The first inductive element branch includes a branch formed by the adjustable inductor L1, or the adjustable inductor L2, or the adjustable inductor L3. It should be understood that Figure 7 illustrates the specific circuit structure of the bias adjustment circuit. The bias adjustment circuit may have other circuit structures, and the embodiments of the present application do not make special limitations on this.

[0141] Referring to Figure 8 , which shows a structural diagram of a gain adjustment circuit. The gain adjustment circuit may include a first resistive element branch and a fourth capacitive element branch. The first resistive element branch includes a branch formed by one, two, or three of the adjustable resistors R6, R7, and R8, and a branch formed by any two of the adjustable resistors R9, R10, and R11. The fourth capacitive element branch includes a branch formed by the adjustable capacitor C8 or the adjustable capacitor C9. It should be understood that Figure 8 illustrates the specific structure of the gain adjustment circuit. The gain adjustment circuit may have other structures, and the embodiments of the present application do not make special limitations on this.

[0142] Based on the above circuit structure, when the embodiments of the present application perform linear adjustment on a single parameter of the frequency response curve without changing the values of other parameters, the operations for specifically performing linear adjustment on a single parameter may include the following several types:

[0143] The first type: The target parameter is the amplitude of the frequency response curve, and the target adjustment circuit includes a gain adjustment circuit and an output matching adjustment circuit; the target adjustment circuit may further include at least one of an input matching adjustment circuit and a bias adjustment circuit. The gain adjustment circuit includes a first resistive element branch, the output matching adjustment circuit includes a first capacitive element branch, the input matching adjustment circuit includes a second capacitive element branch and a second resistive element branch, and the bias adjustment circuit includes a third resistive element branch, a first inductive element branch, and a third capacitive element branch. The control circuit is used to turn on the first resistive element branch to adjust the low-frequency gain of the frequency response curve, and to turn on the first capacitive element branch to compensate for the high-frequency gain of the frequency response curve, and to turn on at least one of the second capacitive element branch, the second resistive element branch, the third resistive element branch, the first inductive element branch, and the third capacitive element branch to correct the frequency deviation of the frequency response curve.

[0144] Among them, in the low-frequency range, the low-frequency gain of the signal can be increased or decreased by adjusting the resistance value. Based on this, the control circuit can turn on the first resistive element branch to change the total impedance of the gain adjustment circuit, thereby adjusting the low-frequency gain of the frequency response curve.

[0145] Among them, the impedance of a capacitive element (such as a capacitor) is relatively low at high frequencies. Therefore, by turning on the first capacitive element branch, an additional path can be provided in the high-frequency range to compensate for the high-frequency gain of the frequency response curve.

[0146] As an example: Capacitive and resistive elements can form a filter to affect the response in a specific frequency range. Therefore, the second capacitive element branch and the second resistive element branch can be used to adjust the resonant frequency and impedance matching of the circuit, thereby correcting the frequency deviation of the frequency response curve.

[0147] As another example: An inductive element (such as an inductor) can be used in a circuit to adjust the phase and frequency response, especially when combined with a capacitor to form a resonant circuit. Therefore, the third resistive element branch, the first inductive element branch, and the third capacitive element branch can be used to correct the frequency deviation of the frequency response curve.

[0148] The above control circuit can selectively turn on or off these element branches through switching elements (such as transistors, relays, etc.). That is to say, corresponding switching elements are provided in each of the above element branches, and these switching elements are controlled by the control circuit.

[0149] More specifically, the control circuit may include a signal processing module. The signal processing module is used to analyze and / or decode the received control signal to determine which element branches need to be turned on. The process of signal processing involves steps such as filtering, amplification, and analog-to-digital conversion (if it is an analog signal). The control circuit may also include a drive circuit. The drive circuit receives instructions from the signal processing module and generates corresponding drive signals. The drive signals are used to control the on and off states of the switching elements (such as MOSFETs, BJTs, relays, etc.) in each element branch.

[0150] Based on the functions of the above control circuit, in this embodiment, the control circuit can analyze the control signal to determine to turn on the switching elements in the first resistive element branch, the first capacitive element branch, the second capacitive element branch, and the second resistive element branch, so as to linearly adjust the amplitude of the frequency response curve.

[0151] Second: The target parameter is the swing amplitude of the frequency response curve. The target adjustment circuit includes a gain adjustment circuit and an output matching adjustment circuit; and, the target adjustment circuit further includes at least one of an input matching adjustment circuit and a bias adjustment circuit.

[0152] The gain adjustment circuit includes a fourth capacitive element branch, the output matching adjustment circuit includes a first capacitive element branch, the input matching adjustment circuit includes a second resistive element branch and a second capacitive element branch, and the bias adjustment circuit includes a third resistive element branch, a first inductive element branch, and a third capacitive element branch.

[0153] The control circuit is used to turn on the fourth capacitive element branch to adjust the swing amplitude of the curve before the extreme frequency of the frequency response curve, turn on the first capacitive element branch to compensate for the high-frequency gain of the frequency response curve; and, turn on the first inductive element branch to compensate for the frequency offset of the frequency response curve caused by the swing amplitude adjustment of the frequency response curve; and, turn on at least one of the second resistive element branch, the second capacitive element branch, the third resistive element branch, and the third capacitive element branch to correct the low-frequency gain drift of the frequency response curve.

[0154] Among them, the capacitive element can affect the phase and amplitude responses in the circuit. Therefore, by turning on the fourth capacitive element branch, the resonant characteristics of the circuit can be adjusted, and then the response amplitude near a specific frequency of the frequency response curve can be adjusted to optimize the swing amplitude of the curve before the frequency response curve.

[0155] Among them, in the high-frequency range, the capacitive element can provide low impedance to increase the high-frequency gain of the frequency response. Therefore, by turning on the first capacitive element branch, the attenuation of high-frequency signals can be compensated to ensure that the gain of the frequency response curve in the high-frequency band reaches the expected level.

[0156] Among them, a reactive component (such as an inductor) can affect the frequency response and phase characteristics in a circuit. Therefore, by turning on the first reactive element branch, the phase response and resonant frequency of the circuit can be adjusted to compensate for the frequency offset problem caused by amplitude adjustment (such as through a capacitive component).

[0157] Among them, a resistive component can change the gain characteristics of the circuit, and a capacitive component can affect the phase and frequency response. Therefore, by selectively turning on at least one of the second resistive element branch, the second capacitive element branch, the third resistive element branch, and the third capacitive element branch, the drift of the low-frequency gain can be corrected to ensure the stability and accuracy of the frequency response curve in the low-frequency band.

[0158] Based on the functions of the above control circuit, in this embodiment, the control circuit can analyze the control signal to determine the switching elements in the fourth capacitive element branch, the first capacitive element branch, the first reactive element branch, and the second resistive element branch to linearly adjust the amplitude of the frequency response curve.

[0159] The third type: The target parameter is the extreme frequency of the frequency response curve, and the target adjustment circuit includes a bias adjustment circuit and an output matching adjustment circuit; the target adjustment circuit further includes at least one of an input matching adjustment circuit and a bias adjustment circuit; the bias adjustment circuit includes a first reactive element branch and a third resistive element branch, the output matching adjustment circuit includes a first capacitive element branch, the gain adjustment circuit includes a fourth capacitive element branch and a first resistive element branch, and the input matching adjustment circuit includes a second capacitive element branch and a second resistive element branch; the control circuit is configured to turn on the first reactive element branch to adjust the extreme frequency of the frequency response curve; and, turn on the third resistive element branch to callback the change in the extreme amplitude caused by the change in the extreme frequency of the frequency response curve; and, turn on the first capacitive element branch to compensate for the high-frequency gain of the frequency response curve; and, turn on at least one of the fourth capacitive element branch, the first resistive element branch, the second capacitive element branch, and the second resistive element branch to correct the low-frequency gain drift of the frequency response curve.

[0160] Among them, a reactive component (such as an inductor) affects the resonant frequency and phase response in the circuit. Therefore, by turning on the first reactive element branch, the resonant characteristics of the circuit can be changed, thereby adjusting the extreme frequency of the frequency response curve. It should be understood that when the extreme frequency changes, it may cause a change in the extreme amplitude, and by turning on the third resistive element branch, the impedance characteristics of the circuit can be adjusted, thereby callback the amplitude change caused by the frequency adjustment.

[0161] A capacitive component can provide a lower impedance in the high-frequency range and can increase the high-frequency gain of the signal. Therefore, by turning on the first capacitive element branch, the attenuation of the high-frequency signal can be compensated to ensure that the gain of the frequency response curve in the high-frequency band reaches the expected level.

[0162] It should be understood that resistive elements can change the gain characteristics of a circuit, while capacitive elements can affect the phase and frequency response. Therefore, by selectively turning on the fourth capacitive element branch, the first resistive element branch, the second capacitive element branch, and the second resistive element branch, the drift of the low-frequency gain of the frequency response curve can be corrected, ensuring the stability and accuracy of the frequency response curve in the low-frequency band.

[0163] Based on the functions of the above control circuit, in this embodiment, the control circuit can analyze the control signal to determine which switch elements in the first inductive element branch, the third resistive element branch, the first capacitive element branch, the fourth capacitive element branch, and the first resistive element branch should be turned on, so as to linearly adjust the swing amplitude of the frequency response curve.

[0164] Fourth, the target parameter is the extreme amplitude of the frequency response curve. The target adjustment circuit includes a gain adjustment circuit, a bias adjustment circuit, an output matching adjustment circuit, and an input matching adjustment circuit; the bias adjustment circuit includes a third resistive element branch and a first inductive element branch, the gain adjustment circuit includes a first resistive element branch, the output matching adjustment circuit includes a first capacitive element branch, and the input matching adjustment circuit includes a second capacitive element branch and a second resistive element branch; the control circuit is used to turn on the third resistive element branch to adjust the extreme amplitude of the frequency response curve; and, turn on the first resistive element branch to callback the change in the low-frequency gain of the frequency response curve; and, turn on the first capacitive element branch to compensate for the high-frequency gain of the frequency response curve; and, turn on the first inductive element branch to callback the drift of the extreme frequency of the frequency response curve; and, turn on the second capacitive element branch, and / or the second resistive element branch, to correct the drift of the low-frequency gain of the frequency response curve.

[0165] Among them, resistive elements can affect the gain characteristics of a circuit. Therefore, by turning on the third resistive element branch, the total impedance of the circuit can be adjusted, thereby changing the extreme amplitude of the frequency response curve.

[0166] It should be understood that the change in the low-frequency gain may be caused by the drift of circuit parameters or other factors. By turning on the first resistive element branch, the low-frequency impedance characteristics of the frequency response curve can be adjusted, thereby callback or compensating for the change in the low-frequency gain.

[0167] It should be understood that capacitive elements can provide a lower impedance in the high-frequency range to increase the high-frequency gain of the frequency response curve. Therefore, by turning on the first capacitive element branch, the attenuation of high-frequency signals can be compensated, ensuring that the gain of the frequency response curve in the high-frequency band reaches the expected level.

[0168] Inductive elements (such as inductors) affect the resonant frequency and phase response of a circuit. By turning on the first inductive element branch, the resonant characteristics of the circuit can be adjusted, thereby callback the drift of the extreme frequency of the frequency response curve.

[0169] A combination of capacitive and resistive elements can form a filter structure that affects the response in a specific frequency range. Therefore, by selectively conducting the second capacitive element branch and the second resistive element branch, the drift of the low-frequency gain can be corrected to ensure the stability and accuracy of the frequency response curve in the low-frequency band.

[0170] Based on the functions of the above control circuit, in this embodiment, the control circuit can analyze the control signal to determine which switch elements in the third resistive element branch, the first resistive element branch, the first capacitive element branch, the first inductive element branch, the second capacitive element branch, and the second resistive element branch should be turned on to linearly adjust the swing of the frequency response curve.

[0171] Based on the above operations, during the linear adjustment of the target parameter in the embodiment of the present application, precise linear adjustment of the target parameter can be achieved through multiple element branches. Among them, some element branches can be used to adjust the target parameter, some element branches can be used to callback the changes caused by other parameters, and the remaining element branches can be used to correct the frequency response curve. Through the coordinated adjustment of multiple element branches in multiple adjustment circuits, the effect of linear adjustment is achieved, improving the accuracy of adjustment. At the same time, it can adapt to various compensation requirements of wide-band and complex frequency response systems, with a wide application range and strong adjustment ability.

[0172] As an example, when adjusting the amplitude of the frequency response curve, the first resistive element branch included in the gain adjustment circuit is responsible for adjusting the amplitude of the frequency response curve. The first capacitive element branch in the output matching adjustment circuit is used to callback the deviation of the high-frequency gain of the frequency response curve caused by adjusting the amplitude of the frequency response curve. Specifically, the first capacitive element branch is used to compensate the high-frequency gain of the frequency response curve. At least one of the second capacitive element branch, the second resistive element branch, the third resistive element branch, the first inductive element branch, and the third capacitive element branch is used to correct the deviation of the frequency offset of the frequency response curve caused by adjusting the amplitude of the frequency response curve.

[0173] As another example, when adjusting the swing of the frequency response curve, the fourth capacitive element branch included in the gain adjustment circuit is used to adjust the curve swing before the extreme frequency. The first capacitive element branch included in the output matching adjustment circuit is used to callback the deviation of the high-frequency gain of the frequency response curve caused by adjusting the swing of the frequency response curve. Specifically, the first capacitive element branch is used to compensate the high-frequency gain of the frequency response curve. The first inductive element branch included in the bias adjustment circuit is used to compensate the frequency offset of the frequency response curve caused by the swing adjustment. At least one of the second resistive element branch, the second capacitive element branch included in the input matching adjustment circuit, the third resistive element branch, and the third capacitive element branch included in the bias adjustment circuit is used to correct the problem of the low-frequency gain deviation of the frequency response curve caused by adjusting the swing of the frequency response curve.

[0174] Embodiments of the present application can respectively adjust the amplitude of the frequency response curve, the swing of the frequency response curve, the extreme frequency of the frequency response curve, and the extreme amplitude of the frequency response curve, meeting the usage requirements of the system for compensating complex frequency response curves, reducing the additional losses and noises introduced by cascading multi-stage equalization circuits in the prior art, and optimizing the system noise index more effectively.

[0175] That is to say, the multi-parameter adjustment device provided by the embodiments of the present application improves the parameter adjustment ability of the system, including the adjustment range and adjustment accuracy; through the coordinated adjustment of multiple components in multiple adjustment circuits, a linear adjustment effect similar to that of the low-frequency band for a single parameter can still be achieved in the high-frequency band, the frequency response curve of the high-frequency radio frequency system can be corrected, and it has strong flexibility and accuracy.

[0176] It should be noted that in the field of digital mobile communication, one of the factors seriously affecting the quality of digital mobile communication is inter-symbol interference. In order to reduce inter-symbol interference and improve the quality of digital communication, signal equalization technology needs to be adopted at the mobile receiving end to improve it. As the power frequency increases, the difficulty of an equalization circuit with a wide adjustment range and high adjustment accuracy also increases sharply, and the problem can also be solved by using the multi-parameter adjustment device provided by the embodiments of the present application.

[0177] Embodiments of the present application also provide a high-frequency radio frequency system, which includes Figures 1 - 2 the parameter adjustment device provided in the above embodiments.

[0178] It should be understood that the high-frequency radio frequency system includes the above parameter adjustment device, and the high-frequency radio frequency system has the same beneficial effects as those of the parameter adjustment device provided in the foregoing Figures 1 - 2 embodiments shown, which will not be elaborated here.

[0179] Referring to Figure 9 , embodiments of the present application also provide a parameter adjustment method, which can be applied to the above high-frequency radio frequency system, and includes the following steps:

[0180] Step S901, the control circuit conducts the target adjustment circuit according to the control signal to linearly adjust the target parameter of the frequency response curve of the system, where the target adjustment circuit includes at least one of an input matching adjustment circuit, an output matching adjustment circuit, a gain adjustment circuit, and a bias adjustment circuit.

[0181] Specifically, this step can be understood according to the description of the above parameter adjustment device, which will not be elaborated here.

[0182] The target parameter of the above frequency response curve may include any one of the amplitude of the frequency response curve, the swing of the frequency response curve, the extreme frequency of the frequency response curve, and the extreme amplitude of the frequency response curve.

[0191] Optionally, the embodiments of the present application can achieve precise linear adjustment of the target parameter in the following manner.

[0192] The first method, the target parameter is the amplitude of the frequency response curve, and the target adjustment circuit includes a gain adjustment circuit and an output matching adjustment circuit; the target adjustment circuit may further include at least one of an input matching adjustment circuit and a bias adjustment circuit.

[0207] S902. According to the adjustment amount of the target parameter and the preset gear configuration information table, determine the element values in each element branch of the target adjustment circuit.

[0208] In the embodiments of the present application, the target parameter and the adjustment amount of the target parameter can be determined according to the linear adjustment requirement of the frequency response curve of the high-frequency radio frequency system. The preset gear configuration information table can be set according to experience or experimental data. The embodiments of the present application do not make special limitations on this.

[0209] Among them, the linear adjustment requirement of the frequency response curve of the high-frequency radio frequency system can be determined according to the high-frequency loss of the system. That is to say, for different linear adjustment requirements of the frequency response curve, different target parameters need to be adjusted to compensate for the high-frequency loss of the system. The linear adjustment requirement may include any one of changing the low-frequency gain of the frequency response curve to the target gain, changing the curve swing amplitude before the extreme frequency of the frequency response curve to the target swing amplitude, changing the extreme frequency of the frequency response curve to the target extreme frequency, and changing the extreme amplitude of the frequency response curve to the target extreme amplitude.

[0210] It should be understood that the target gain, target swing, target extreme frequency, and target extreme amplitude can be determined according to the high-frequency loss of the system.

[0211] Based on this, the adjustment amount of the target parameter can be determined, and then the component values in each component branch of the target adjustment circuit can be determined. Then, the component values in each branch are adjusted according to the component values in each branch to achieve precise adjustment of the target parameter in the frequency response curve.
