Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to parameter adjustment devices, methods, equipment, high-frequency radio frequency systems and storage media. Background Art

[0002] In high-frequency RF systems, due to the high-frequency band loss of the analog front end, an equalization circuit is required to compensate for the high-frequency loss. Compared with digital equalization, improving the flatness of the analog channel frequency response through analog equalization can effectively improve the signal-to-noise ratio deterioration during the back-end AD (Analog-to-Digital) sampling process.

[0003] Analog equalization is to achieve high-frequency warping of the frequency response curve by introducing a coupling structure between two operational amplifiers. Due to the use of a peripheral lap adjustment circuit, this method can only work at a lower frequency. In order to increase the operating frequency, an equalization circuit in the form of a current transformer equalization loop is proposed. This structure lowers the low-frequency gain of the amplifier in the differential amplifier circuit through a degeneration loop placed between the emitters of the two transistors in the differential amplifier circuit, thereby increasing the high-frequency gain. However, the current current transformer equalization loop adjustment parameters are single and linear adjustment cannot be achieved. Summary of the invention

[0004] The present application provides a parameter adjustment device, method, equipment, high-frequency radio frequency system and storage medium, which are used to provide a technical solution that can adjust multiple parameters of a frequency response curve and can linearly adjust each of the multiple parameters.

[0005] In a first aspect, the present application provides a parameter adjustment device, which is applied to a high-frequency radio frequency system, and the device includes a control circuit, an input matching adjustment circuit, an output matching adjustment circuit, a gain adjustment circuit, and a bias adjustment circuit;

[0006] The control circuit is respectively connected with the input matching adjustment circuit, the output matching adjustment circuit, the gain adjustment circuit and the bias adjustment circuit;

Based on this, the linear adjustment of a single parameter of the frequency response curve can be achieved. The present application can change the target adjustment circuit that is turned on by changing the control signal of the control circuit, thereby changing the target parameter of the frequency response curve, so as to linearly adjust multiple parameters of the frequency response curve.

And the adjustment process achieves the effect of linear adjustment of the swing of the frequency response curve through the coordinated adjustment of multiple component branches in multiple adjustment circuits, thereby improving the accuracy of the adjustment.

[0095] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

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

[0098] High frequency radio frequency system: 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 signal.

[0100] Frequency response curve: It is a graphical representation that describes the gain or response characteristics of a system at different frequencies. Frequency response curves are usually plotted with frequency as the horizontal axis and gain or amplitude as the vertical axis. By analyzing the frequency response curve, you can understand the performance of the system at different frequencies.

[0101] Linear adjustment: It means that when a single parameter of the frequency response curve is changed, the values ​​of other parameters do not change, and the curve trend does not change.

[0102] Linear Regulation

[0103] The parameter adjustment device improved in the embodiment of the present application is applied to a high-frequency and high-speed radio frequency system 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 the requirements of high-precision linear adjustment to ensure that the high-frequency loss compensation can meet the expected performance standards and avoid excessive or insufficient compensation.

[0104] Specifically, in order to achieve the expected performance standards, when adjusting the amplitude, the swing and extreme frequency remain unchanged, and the frequency response curve is lifted as a whole; when adjusting the swing, the amplitude and extreme frequency remain unchanged, the low-frequency gain of the frequency response curve remains unchanged, and the gain increase changes with the frequency; when adjusting the extreme frequency, the amplitude and extreme amplitude remain unchanged, and the frequency response curve extreme frequency point frequency shifts; when adjusting the extreme amplitude, the amplitude, swing, and extreme frequency remain unchanged, and the frequency response curve basically overlaps before reaching the extreme value, and only the extreme amplitude changes. However, in high-frequency and high-speed RF systems, the adjustment of peaking is limited by high-frequency parasitics and cannot be achieved by adjusting a single component value like in low-frequency systems.

[0105] In view of the above problems, the present application has designed 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 among 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. The present application can also achieve linear adjustment of a single parameter by adjusting multiple components in multiple adjustment circuits. The linear adjustment can be a high-frequency linear adjustment.

[0106] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0107] Reference Figure 1 An embodiment of the present application provides a parameter adjustment device for use in a high-frequency radio frequency system. The device includes a control circuit, an input matching adjustment circuit, an output matching adjustment circuit, a gain adjustment circuit, and a bias adjustment circuit.

[0108] The control circuit is respectively connected with the input matching adjustment circuit, the output matching adjustment circuit, the gain adjustment circuit and the bias adjustment circuit.

[0109] The control circuit is used to turn on the target adjustment circuit according to the control signal to linearly adjust the target parameters of the frequency response curve of the system, wherein 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.

[0110] The above-mentioned control circuit is used to receive an external control signal and turn on at least one of the input matching adjustment circuit, the output matching adjustment circuit, the gain adjustment circuit and the bias adjustment circuit according to the control signal to linearly adjust the frequency response curve of the system, thereby optimizing the performance of the RF system to meet the needs of different application scenarios.

[0111] In the embodiment of the present application, the control circuit can turn on the target adjustment circuit according to the control signal to linearly adjust the target parameter of the frequency response curve, based on which the linear adjustment of a single parameter of the frequency response curve can be achieved. Furthermore, in the embodiment of the present application, the control signal of the control circuit can be changed to change the turned-on target adjustment circuit, thereby changing the target parameter of the frequency response curve, so as to linearly adjust multiple parameters of the frequency response curve.

[0112] In some examples, the above-mentioned input matching adjustment circuit, output matching adjustment circuit, gain adjustment circuit and bias adjustment circuit can be applied to a single-stage differential amplifier circuit. Specifically: Figure 2 , the single-stage differential amplifier circuit may include: (1) input terminals, which are usually two and used to receive two input signals respectively. (2) active devices (also called current amplification structures): usually include two transistors (which may be bipolar transistors or field effect transistors), whose emitters or sources are connected together to form a differential pair. (3) current source: a constant current source is connected between the common terminal (emitter or source) of the two transistors and the ground to provide bias current. (4) load resistor: the collector or drain of each transistor is connected to a load resistor. (5) output terminal, the two output terminals are respectively derived from the collector or drain of the two transistors to output differential signals.

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

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

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

[0116] Optionally, the input matching adjustment circuit can be used to adjust the matching impedance of the input end of the single-stage differential amplifier circuit, the output matching adjustment circuit can be used to adjust the matching impedance of the input end of the single-stage differential amplifier circuit, and the gain adjustment circuit can be used to adjust the gain of the system. 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 amplifier structure.

[0117] Based on the above description, the embodiment of the present application introduces an input matching adjustment circuit, an output matching adjustment circuit, a gain adjustment circuit, and a bias adjustment circuit between the input end, the output end, the current amplification structure, the current source, and the load resistor of the single-stage differential amplifier circuit, respectively. At least one of these circuits can adjust the target parameter of the frequency response curve according to the linear adjustment requirement of the frequency response curve of the system, based on which the linear adjustment of a single parameter can be achieved. It should be understood that when the linear adjustment requirement of the frequency response curve of the system changes, the corresponding target parameter that needs to be adjusted will also change accordingly, so 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 requirement may include: 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-mentioned 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 parameter 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 the low-frequency gain of the frequency response curve needs to be changed to a target gain, the 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 first resistive element branch, 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 that it has the same impedance for signals of all frequencies. Gain refers to the ratio of the output signal amplitude to the input signal amplitude. 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, the resistance value of the resistive element in the first resistive element branch can be adjusted so that the amplitude of the frequency response curve within a specific frequency range reaches the expected level.

[0124] When the curve swing before the extreme frequency of the frequency response curve needs to be changed to the target swing, the swing of the frequency response curve can be adjusted. At this time, the target adjustment circuit at least includes a gain adjustment circuit, and the gain adjustment circuit includes a fourth capacitive element branch, and the fourth capacitive element branch includes a capacitive element, and the capacitive element is used to adjust the swing of the frequency response curve.

[0125] It should be understood that capacitive elements (such as capacitors) are used to store and release charge in circuits and have frequency-dependent impedance characteristics. Their impedance decreases as the frequency increases. Due to this frequency dependence, capacitors have different effects on signals of different frequencies. The swing of the frequency response curve refers to the change in the signal amplitude within a specific frequency range. Therefore, the amplitude of the signal can be adjusted through capacitive elements, thereby adjusting the signal swing within a specific frequency range.

[0126] When the extreme frequency of the frequency response curve needs to be changed 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, the first inductive element branch includes an inductive element, and the inductive element is used to adjust the extreme frequency of the frequency response curve.

[0127] It should be understood that inductive elements (such as inductors) are used to store and release magnetic energy in circuits, and their impedance (called reactance) increases with increasing frequency. Due to this frequency dependence, inductors have different effects on signals of different frequencies, and 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 the extreme amplitude of the frequency response curve needs to be changed 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, the third resistive element branch includes a resistive element, and the resistive element is used to adjust the extreme amplitude of the frequency response curve.

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

[0130] In one example, the resistive element of any circuit in 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 embodiment of the present application can set the component value in the corresponding adjustment circuit according to different adjustment values ​​of the adjustment parameters to achieve 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 according to the difference between the current low-frequency gain value and the target gain value of the frequency response curve by querying the preset gear configuration information table. Among them, the preset gear configuration information table can be set according to experience or experimental data, and the embodiment of the present application does not make any special limitation to this.

[0132] For another example, when the extreme frequency of the frequency response curve needs to be changed to the target extreme frequency, the inductance value of the variable inductor in the bias adjustment circuit can be determined according to the difference between the current extreme frequency of the frequency response curve and the target extreme frequency, so as 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 according to the difference between the current extreme frequency of the frequency response curve and the target extreme frequency by querying the preset gear configuration information table.

[0133] According to the above, the parameter adjustment device provided in the embodiment of the present application is applied to the scenario where the mid-high frequency loss needs to be compensated in the 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 do not change, and the curve change trend does not change. Based on this, refer to Figure 3a , the embodiment of the present application needs to meet the requirement that when the amplitude is adjusted, the swing amplitude and the extreme frequency remain unchanged, the gain of the frequency response curve is increased, and the shape of the frequency response curve remains unchanged; reference Figure 3b , the embodiment of the present application needs to meet the requirements that when adjusting the swing amplitude, the amplitude and extreme frequency remain unchanged, the low-frequency gain of the frequency response curve remains unchanged, and the gain increase amplitude changes with the frequency; reference Figure 3c, the embodiment of the present application needs to satisfy that when adjusting the extreme frequency, the amplitude and extreme amplitude remain unchanged, and the frequency of the extreme frequency point of the frequency response curve shifts; reference Figure 3d , the embodiment of the present application needs to meet the requirement that when adjusting the extreme value amplitude, the amplitude, swing amplitude, and extreme value frequency remain unchanged, and the frequency response curve basically overlaps before reaching the extreme value, and only the extreme value amplitude changes.

[0134] It should be understood that in high-frequency systems, peaking adjustment is limited by high-frequency parasitics, and it is not possible to achieve linear adjustment of the peaking curve by adjusting a single component value like in low-frequency systems. The parameter adjustment device proposed in the embodiment of the present application can effectively solve this problem. When the signal enters the system, it is affected by high-frequency insertion loss (including but not limited to passive transmission loss and high-frequency gain roll-off of active structures), and the frequency response decreases as the frequency increases. Figure 4 As shown in curve 1. At this time, a frequency response curve is added to the system, and a peaking curve exists at high frequencies, such as Figure 4 As shown in the middle curve 3. After compensation, the high frequency of the system frequency response curve is pulled up, as shown in Figure 4 As shown in curve 2, 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.

[0135] It is worth noting that the above-mentioned peaking can refer to the phenomenon that the system gain has a peak within a specific frequency range. The gain of a certain frequency band in the frequency response can be increased by peaking to compensate for the attenuation of the frequency response of other parts of the high-frequency system.

[0136] Optionally, the embodiment of the present application can implement linear adjustment of target parameters in the following manner.

[0137] First, the structures of the various regulating circuits are described.

[0138] Reference 5 shows a structural diagram of an input matching adjustment circuit, which includes a second capacitive element branch and a second resistive element branch; wherein the second capacitive element branch may include an adjustable capacitor C1, or an adjustable capacitor C2, or a branch formed by connecting the adjustable capacitors C1 and C2 in series, and the second resistive element branch may include an adjustable resistor R1, or an adjustable resistor R2, or a branch formed by connecting the adjustable resistors R1 and R2 in series. It should be understood that Figure 5 The specific circuit structure of the input matching adjustment is exemplified in the figure.

[0139] Reference Figure 6, shows a structural diagram of an output matching adjustment circuit, the output matching adjustment circuit includes a first capacitive element branch; wherein the first capacitive element branch may include a branch formed by connecting one or any two of the adjustable capacitors C3, C4, C5, and C6 in series. It should be understood that Figure 6 The specific circuit structure of the output matching adjustment circuit is exemplified in the figure. The output matching adjustment circuit may also have other structures, which are not particularly limited in the embodiments of the present application.

[0140] Reference Figure 7 , shows a structural diagram of a bias adjustment circuit, which 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 an adjustable resistor R3, or, an adjustable resistor R4, or, an adjustable resistor R4, the third capacitive element branch includes a branch formed by an adjustable capacitor C7, and the first inductive element branch includes a branch formed by an adjustable inductor L1, or, an adjustable inductor L2, or, an adjustable inductor L3. It should be understood that Figure 7 The specific circuit structure of the bias adjustment circuit is exemplified in the figure. The bias adjustment circuit may have other circuit structures, and the embodiments of the present application do not specifically limit this.

[0141] Reference Figure 8 , shows a structural diagram of a gain adjustment circuit, which 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, and 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 The specific structure of the gain adjustment circuit is exemplified in the figure. The gain adjustment circuit may have other structures, and the embodiments of the present application do not specifically limit this.

[0142] Based on the above circuit structure, when the embodiment of the present application performs linear adjustment on a single parameter of the frequency response curve, the values ​​of other parameters are not changed. The specific operations of linear adjustment on a single parameter may include the following:

[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 also 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 change the total impedance of the gain adjustment circuit by turning on the first resistive element branch, thereby adjusting the low-frequency gain of the frequency response curve.

[0145] The impedance of the capacitive element (such as a capacitor) is relatively low at high frequencies, so the first capacitive element branch can be turned on to provide an additional path 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: inductive elements (such as inductors) can be used in circuits to adjust phase and frequency response, especially when combined with capacitors 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 control circuit can selectively turn on or off the component branches through switch elements (such as transistors, relays, etc.), that is, each component branch is provided with a corresponding switch element, and the switch elements are controlled by the control circuit.

[0149] More specifically, the control circuit may include a signal processing module, which is used to analyze and / or decode the received control signal to determine which component branches need to be turned on, and the signal processing process involves filtering, amplification, analog-to-digital conversion (if it is an analog signal), etc. The control circuit may also include a drive circuit, which receives instructions from the signal processing module and generates a corresponding drive signal, and the drive signal is used to control the conduction and disconnection of the switch elements (such as MOSFET, BJT, relay, etc.) in each component branch.

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

[0151] The second type: the target parameter is the swing 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 also 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 curve swing 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 deviation of the frequency response curve caused by the swing 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 response in the circuit, so the resonance characteristics of the circuit can be adjusted by turning on the fourth capacitive element branch, and then the response amplitude near a specific frequency of the frequency response curve can be adjusted to optimize the front curve swing of 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 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.

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

[0157] Among them, the resistive element can change the gain characteristics of the circuit, and the capacitive element can affect the phase and frequency response. Therefore, by selectively conducting 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 determine to turn on the switch elements in the fourth capacitive element branch, the first capacitive element branch, the first inductive element branch and the second resistive element branch by analyzing the control signal to linearly adjust the swing of the frequency response curve.

[0159] The third type: the target parameter is the extreme frequency of the frequency response curve, the target adjustment circuit includes a bias adjustment circuit and an output matching adjustment circuit; the target adjustment circuit also includes at least one of an input matching adjustment circuit and a bias adjustment circuit; the bias adjustment circuit includes a first inductive 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 used to turn on the first inductive element branch to adjust the extreme frequency of the frequency response curve; and turn on the third resistive element branch to adjust 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, the inductive element (such as inductance) affects the resonant frequency and phase response in the circuit. Therefore, by turning on the first inductive 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 calling back the amplitude change caused by the frequency adjustment.

[0161] The capacitive element can provide 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 the resistive element can change the gain characteristics of the circuit, while the capacitive element can affect the phase and frequency response. Therefore, by selectively conducting 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 to ensure 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 determine to turn on the 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 by analyzing the control signal to linearly adjust the swing of the frequency response curve.

[0164] The fourth type, the target parameter is the extreme amplitude of the frequency response curve, and 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 adjust the low-frequency gain change 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 adjust 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 low-frequency gain drift of the frequency response curve.

[0165] Among them, the resistive element can affect the gain characteristics of the 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 of 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 adjusting or compensating for the change of low-frequency gain.

[0167] It should be understood that the capacitive element 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 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.

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

[0169] The combination of capacitive and resistive elements can form a filter structure and affect 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 determine to turn on the 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 by analyzing the control signal to linearly adjust the swing of the frequency response curve.

[0171] Based on the above operations, in the process of linearly adjusting the target parameters, the embodiment of the present application can accurately linearly adjust the target parameters through multiple component branches. Among them, some component branches can be used to adjust the target parameters, some component branches can be used to call back the changes caused by other parameters, and the remaining component branches can be used to correct the frequency response curve. Through the coordinated adjustment of multiple component branches in multiple adjustment circuits, the effect of linear adjustment is achieved, the accuracy of adjustment is improved, and it can adapt to various compensation requirements of wide-band and complex frequency response systems, with a wide range of applications and strong adjustment capabilities.

[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, and the first capacitive element branch in the output matching adjustment circuit is used to adjust 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 for 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 deviation 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 swing of the curve before the extreme frequency, and the first capacitive element branch included in the output matching adjustment circuit is used to adjust 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 for the high-frequency gain of the frequency response curve. The first inductive element branch included in the bias adjustment circuit is used to compensate for the frequency deviation of the frequency response curve caused by the swing adjustment, and at least one of the second resistive element branch, the second capacitive element branch included in the input matching adjustment circuit, and the third resistive element branch and the third capacitive element branch included in the bias adjustment circuit are used to correct the low-frequency gain deviation of the frequency response curve caused by adjusting the swing of the frequency response curve.

[0174] The embodiments of the present application can 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, respectively, thereby meeting the system's use requirements for complex frequency response curve compensation, reducing the additional loss and noise introduced by the cascade of multi-stage equalization circuits in the prior art, and can further optimize the system noise index.

[0175] That is to say, the multi-parameter adjustment device provided in the embodiment of the present application improves the parameter adjustment capability 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 for a single parameter similar to that in the low-frequency band can still be achieved in the high-frequency band, and the frequency response curve of the high-frequency RF system can be corrected, with strong flexibility and accuracy.

[0176] It is worth noting that in the field of digital mobile communications, one of the factors that seriously affect the quality of digital mobile communications is inter-symbol interference. In order to reduce inter-symbol interference and improve the quality of digital communications, it is necessary to adopt signal equalization technology at the mobile receiving end to improve it. With the increase of power frequency, the difficulty of equalization circuits with a wide adjustment range and high adjustment accuracy also increases sharply, and the multi-parameter adjustment device provided by the embodiment of the present application can also solve this problem.

[0177] The present application also provides a high-frequency radio frequency system, which includes Figure 1-Figure 2 The parameter adjustment device provided in the illustrated embodiment.

[0178] It should be understood that the high-frequency radio frequency system includes the above-mentioned parameter adjustment device, and the high-frequency radio frequency system and the above-mentioned Figure 1-Figure 2 The beneficial effects of the parameter adjustment device provided in the illustrated embodiment are the same and will not be described in detail here.

[0179] Reference Fig. 9 The embodiment of the present application also provides a parameter adjustment method, which can be applied to the above-mentioned high-frequency radio frequency system, comprising the following steps:

[0180] In step S901, the control circuit turns on the target adjustment circuit according to the control signal to linearly adjust the target parameters of the frequency response curve of the system, wherein 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 based on the description of the above parameter adjustment device, and will not be described in detail here.

[0207] S902, determining the component values ​​in each component branch in the target adjustment circuit according to the adjustment amount of the target parameter and the preset gear configuration information table.

[0208] In the embodiment of the present application, the target parameter and the adjustment amount of the target parameter can be determined according to the linear adjustment requirements 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, and the embodiment of the present application does not make any special limitation on this.

[0209] Among them, the linear adjustment requirement of the frequency response curve of the high-frequency RF 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: 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.

[0210] It should be understood that the target gain, the target swing, the target extreme frequency, and the 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 in the target adjustment circuit can be determined, and the component values ​​in each branch can be adjusted according to the component values ​​in each branch to achieve precise adjustment of the target parameter in the frequency response curve.
