Description

Technical Field

[0001] This invention relates to amplifiers, and more particularly to a method and system for optimizing amplifier system performance. Background Technology

[0002] Traditionally, amplifier operation requires configuring a quiescent operating point (QOP). Once the QOP is configured, the amplifier's specifications are essentially determined. At a fixed QOP, the amplifier's specifications remain unchanged; the gain and output capability are fixed values. For an amplifier, the QOP for maximum output capability and the QOP for maximum gain often do not overlap. A single QOP cannot simultaneously achieve both maximum output capability and maximum gain. That is, an amplifier with a single QOP can only choose one between maximum output capability and maximum gain. However, there are many situations where it is necessary to adjust the amplifier's QOP voltage configuration. For example, in a receiver's front-end low-noise amplifier module, to reduce the system's noise figure, a high gain is required for the cascaded low-noise amplifier. However, when the preceding signal is too large, to ensure linearity, the amplifier's output capability takes higher priority. Summary of the Invention

Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0061] Example 1:

[0062] This embodiment provides a method for optimizing amplifier system performance, such as... Figure 2 As shown, it includes:

[0063] S1: Obtain the frequency parameters of the signal to be amplified;

[0064] S2: Obtain the target bias voltage corresponding to the preset frequency voltage table according to the frequency parameters;

[0065] S3: Adjust the bias voltage of the amplifier to the target bias voltage so that the frequency of the signal reaches the target adjustment value after being amplified by the amplifier.

[0066] Traditionally, amplifier operation requires configuring a quiescent operating point (QOP). Once the QOP is configured, the amplifier's specifications are essentially determined. At a fixed QOP, the amplifier's specifications remain unchanged; the gain and output capability are fixed values. For an amplifier, the QOP for maximum output capability and the QOP for maximum gain often do not overlap. A single QOP cannot simultaneously achieve both maximum output capability and maximum gain. That is, an amplifier with a single QOP can only choose one between maximum output capability and maximum gain. However, there are many situations where it is necessary to adjust the amplifier's QOP voltage configuration. For example, in a receiver's front-end low-noise amplifier module, to reduce the system's noise figure, a high gain is required for the cascaded low-noise amplifier. However, when the preceding signal is too large, to ensure linearity, the amplifier's output capability takes higher priority.

[0067] Therefore, in this embodiment, by adjusting the amplifier bias voltage, the output signal is adjusted, thereby enabling the amplifier to adapt to power requirements in various scenarios. Specifically, in applications involving RF signal amplification, this system typically includes at least: a frequency discrimination module that detects the center frequency of the input RF signal to be amplified and transmits the result to a control module. The type of its output depends on the type that the control module can recognize; it can be either a digital signal or an analog signal. The system also receives frequency parameters from the frequency discrimination module to determine the quiescent operating point and then controls the bias voltage adjustment module to regulate the voltage.

[0068] Example 2:

[0069] This embodiment provides a method for optimizing amplifier system performance, such as... Figure 3 As shown, it includes:

[0070] S1: Obtain the frequency parameters of the signal to be amplified;

[0071] S2-1: Determine the mode of the amplifier;

[0072] S2-2: When the amplifier is in maximum output power mode, obtain the regulator code of the frequency parameter in the preset maximum output voltage regulator code table;

[0073] S2-3: When the amplifier is in maximum gain power mode, obtain the regulator code of the frequency parameter in the preset maximum gain voltage regulator code table;

[0074] S3-1: Obtain the corresponding voltage regulator according to the regulator code;

[0075] S3-2: Switch to the voltage regulator to adjust the amplifier's bias voltage to the target bias voltage.

[0076] In this preferred embodiment, the amplifier's output task is generally either to output at maximum output power or at maximum gain. Therefore, in general, setting only two different modes is sufficient to meet the device's needs. Specifically, only one maximum output power mode and one maximum gain power mode are set. The correspondence between voltage and frequency is generally represented and stored using a one-to-one correspondence table.

[0077] Specifically, in actual use, two tables are stored in the memory connected to the voltage control module, representing the voltage parameters in the maximum output mode and the voltage parameters in the maximum gain mode, respectively. These are generally pre-tested and planned, showing the static operating points corresponding to the maximum output power and maximum gain in different frequency bands. A correspondence table is established between the frequency points and the switching codes of the static operating points corresponding to the maximum output power and maximum gain, which is then used by the control module for querying and comparison.

[0078] Frequency discrimination of the input signal is real-time. When the frequency of the RF signal to be amplified remains unchanged, the switch code obtained by the control module will not change. When the frequency discrimination result of the RF signal to be amplified changes, the control module queries the frequency-static operating point-switch code lookup table of the corresponding mode in the storage module to obtain the new switch code, and controls the bias voltage adjustment module to output the corresponding static operating point voltage configuration, thereby adjusting the amplifier's operating state to achieve the output specifications of the operating mode.

[0079] When voltage needs to be adjusted, the corresponding voltage value is obtained by looking up a table, and then adjusted by a voltage regulator to control the corresponding voltage output.

[0080] In practice, for ease of use, a switch array approach can be used to implement the voltage regulator. This involves connecting n pre-adjusted bias voltage modules using switches. Each bias voltage module outputs a pre-set static operating point voltage configuration, which, combined with control information from control module 2, adjusts the bias voltage to regulate the static operating point. Specifically, voltage division using resistors regulates the amplifier's power. Switches determine which resistor to use for voltage division, thus regulating the voltage and consequently the power. More specifically, by obtaining the regulator code, the appropriate switch and path can be determined, allowing for the selection of suitable voltage divider resistors and a suitable voltage divider circuit to regulate the power. Similarly, other voltage regulation methods can be used to regulate the amplifier voltage as technology advances.

[0081] Example 3:

[0082] This embodiment provides a method for optimizing amplifier system performance, such as... Figure 4 As shown, it includes:

[0083] S0-1: Measure the static operating point of the amplifier at each frequency point; the frequency points are evenly distributed across the entire operating frequency band of the amplifier; the interval between each frequency point is the amplifier's operating frequency step;

[0084] S0-2: Obtain the target adjustment value;

[0085] S0-3: Obtain the static operating range based on the target adjustment value and the amplifier's static operating point; within the static operating range, the amplifier's maximum output power or maximum gain is higher than the target adjustment value;

[0086] S0-4: Obtain the intersection of each of the static operating ranges, and merge the amplifier static operating points according to the intersection; the merged amplifier static operating points are located within the intersection; the number of amplifier static operating points is equal to the number of voltage regulators.

[0087] S0-5: Construct the frequency voltmeter based on the amplifier's quiescent operating point.

[0088] S1: Obtain the frequency parameters of the signal to be amplified;

[0089] S2-1: Determine the mode of the amplifier;

[0090] S2-2: When the amplifier is in maximum output power mode, obtain the regulator code of the frequency parameter in the preset maximum output voltage regulator code table;

[0091] S2-3: When the amplifier is in maximum gain power mode, obtain the regulator code of the frequency parameter in the preset maximum gain voltage regulator code table;

[0092] S3-1: Obtain the corresponding voltage regulator according to the regulator code;

[0093] S3-2: Switch to the voltage regulator to adjust the amplifier's bias voltage to the target bias voltage.

[0094] In this preferred embodiment, specifically in the construction of the voltmeter, the target values ​​for adjusting the amplifier's specifications in both maximum output and maximum gain modes are generally determined first. Then, across the amplifier's entire operating frequency band, in minimum frequency steps, the amplifier's static operating point is measured at each frequency point based on either the maximum output or maximum gain target value. The voltmeter is then constructed based on the measurement results.

[0095] Meanwhile, since the table is constructed using the minimum step size, the entire table will be very large. Therefore, during the construction process, it is also necessary to measure the range of the amplifier's static operating point for each frequency point. The amplifier's output power or gain within this range must be higher than the corresponding target value. The range of the amplifier's static operating point for each frequency point is merged according to the amplifier's maximum output or maximum gain modes to obtain the minimum number of amplifier static operating points (U1.Un voltages). This reduces the total number of static operating points that need to be configured, simplifies the required voltage divider circuit, and reduces the number of switches.

[0096] This embodiment effectively reduces the total number of static operating points that need to be configured by merging, thereby reducing the number of voltage regulators, reducing system cost, reducing complexity, and improving system reliability.

[0097] Example 5:

[0098] This embodiment provides a system for optimizing amplifier system performance, including:

[0099] Frequency discrimination module 1 is used to obtain the frequency parameters of the signal to be amplified;

[0100] Control module 2 is used to obtain the target bias voltage corresponding to the preset frequency voltage table according to the frequency parameters;

[0101] The bias voltage adjustment module 3 is used to adjust the bias voltage of the amplifier 4 to the target bias voltage so that the frequency of the signal reaches the target adjustment value after being amplified by the amplifier 4.

[0102] The frequency parameter is the center frequency of the RF signal that needs to be amplified.

[0103] Traditionally, amplifier operation requires configuring a quiescent operating point (QOP). Once the QOP is configured, the amplifier's specifications are essentially determined.

[0104] Therefore, in this embodiment, by adjusting the amplifier bias voltage, the output signal is adjusted, thereby enabling amplifier 4 to adapt to power requirements in various scenarios. Specifically, it is generally used for amplifying RF signals. This system typically includes at least: a frequency discrimination module 1, which detects the center frequency of the input RF signal to be amplified and transmits the result to a control module 2.

The system also receives frequency parameters from the frequency discrimination module 1 to determine the static operating point, and then controls the bias voltage adjustment module 3 to adjust the voltage.

[0105] Preferably, the control module 2 is specifically used to, when the amplifier 4 is in the maximum output power mode, obtain the regulator code of the frequency parameter in the preset maximum output voltage regulator code table;

[0106] When the amplifier is in maximum gain power mode, the regulator code of the frequency parameter in the preset maximum gain voltage regulator code table is obtained;

[0107] The bias voltage regulation module 3 specifically includes: a regulator encoding module, used to obtain the corresponding voltage regulator according to the regulator encoding, wherein each regulator encoding corresponds to one voltage regulator;

[0108] Voltage control module 2 is used to switch to the voltage regulator to adjust the bias voltage of the amplifier to the target bias voltage.

[0109] The voltage control module 2 is a one-to-many switch;

[0110] The voltage regulator is the switch position;

[0111] Each regulator code has a unique correspondence with the gear position of the bias voltage regulation module;

[0112] When the target switch is switched to, the bias voltage is adjusted to the target bias voltage.

[0113] In this preferred embodiment, the amplifier 4 typically outputs power either at maximum output power or at maximum gain. Therefore, in practice, setting only two different modes is sufficient to meet the device's requirements. Specifically, only one maximum output power mode and one maximum gain power mode are set. The correspondence between voltage and frequency is typically represented and stored using a one-to-one table.

[0114] Specifically, in actual use, two tables are stored in the memory connected to the voltage control module 2, representing the voltage parameters in the maximum output mode and the voltage parameters in the maximum gain mode, respectively.

A correspondence table is established between the frequency points and the switching codes of the static operating points corresponding to the maximum output power and maximum gain, which is then queried and compared by the control module 2.

[0115] Frequency discrimination of the input signal is real-time. When the frequency of the RF signal to be amplified remains unchanged, the switch code obtained by the control module 2 will not change. When the frequency discrimination result of the RF signal to be amplified changes, the control module 2 queries the frequency-static operating point-switch code lookup table of the corresponding mode in the storage module to obtain the new switch code, and controls the bias voltage adjustment module to output the corresponding static operating point voltage configuration, thereby adjusting the operating state of the amplifier 4 to achieve the output specifications of the operating mode.

[0116] When voltage needs to be adjusted, the corresponding voltage value is obtained by looking up a table, and then adjusted by a voltage regulator to control the corresponding voltage output.

[0117] In practice, for ease of use, a switch array approach can be used to implement the voltage regulator. This involves connecting n pre-adjusted bias voltage modules using switches. Each bias voltage module outputs a pre-set static operating point voltage configuration, which, combined with the control information from control module 2, adjusts the bias voltage to regulate the static operating point. Specifically, voltage division is achieved through resistors, thereby regulating the power of amplifier 4. The switches determine which resistor to use for voltage division, thus regulating the voltage and consequently the power. More specifically, by obtaining the regulator code, the appropriate switch and path can be determined, allowing for the selection of suitable voltage-dividing resistors and a suitable voltage-dividing circuit to regulate the power. Similarly, other types of voltage regulation methods can be used to regulate the voltage of amplifier 4, depending on technological advancements.

[0118] Example 6:

[0119] This embodiment provides a system for optimizing amplifier system performance. Based on embodiment 5, it further includes: an operating point measurement module for measuring the static operating point of the amplifier at each frequency; the frequency points are uniformly distributed across the entire operating frequency band of the amplifier 4; the interval between each frequency point is the amplifier operating frequency step;

[0120] The voltmeter construction module constructs the frequency voltmeter based on the amplifier's static operating point.

[0121] The voltmeter reduction module specifically includes: an adjustment value acquisition module, used to acquire the target adjustment value;

[0122] The operating range measurement module is used to obtain the static operating range based on the target adjustment value and the amplifier's static operating point; within the static operating range, the maximum output power or maximum gain of the amplifier 4 is higher than the target adjustment value;

[0123] The operating point merging module is used to obtain the intersection of each of the static operating ranges, and merge the amplifier static operating points according to the intersection; the merged amplifier static operating points are located within the intersection; the number of amplifier static operating points is equal to the number of voltage regulators.

[0124] In this preferred embodiment, specifically in the construction of the voltmeter, the target values ​​for adjusting the amplifier 4 in both maximum output and maximum gain modes are generally determined first. These target values ​​are the maximum output target value and the maximum gain target value. Then, across the entire operating frequency range of the amplifier, in minimum frequency steps, the quiescent operating point of the amplifier is measured at each frequency point based on the maximum output target value or the maximum gain target value. The voltmeter is then constructed based on the measurement results.

[0125] Meanwhile, since the table is constructed using the minimum step size, the entire table will be very large. Therefore, during the construction process, it is also necessary to measure the range of the amplifier's static operating point for each frequency point. The amplifier's output power or gain within this range must be higher than the corresponding target value. The range of the amplifier's static operating point for each frequency point is merged according to the amplifier's maximum output or maximum gain modes to obtain the minimum number of amplifier static operating points (U1.Un voltages). This reduces the total number of static operating points that need to be configured, simplifies the required voltage divider circuit, and reduces the number of switches.

[0126] This embodiment effectively reduces the total number of static operating points that need to be configured by merging, thereby reducing the number of voltage regulators, reducing system cost, reducing complexity, and improving system reliability.

[0127] Example 7:

[0128] This embodiment provides a system for optimizing amplifier system performance, based on embodiment 6 or 7, such as... Figure 5 , 6 As shown, the output power and gain of the GaN power amplifier (Vd = +28V) in the frequency band (200MHz to 200.15MHz) at different quiescent operating points (gate voltage Vg) under the conditions of maximum power output and maximum gain modes are tested.

[0134] After merging the static operating points across the entire frequency band, there are three static operating points in the maximum power output mode: operating point 1 (gate voltage -2.62V), operating point 2 (gate voltage -2.74V), and operating point 3 (gate voltage -2.46V).

[0135] The maximum gain mode has four static operating points: operating point 4 (gate voltage -2.64V), operating point 5 (gate voltage -2.71V), operating point 6 (gate voltage -2.77V), and operating point 7 (gate voltage -2.60V).

[0136] If control module 2 selects the amplifier in maximum power output mode, the input signal passes through frequency discriminator module 1, resulting in a signal with a center frequency of 200.11MHz. The static operating point is selected as operating point 3, and the switch is switched to Vg = -2.46V. At this operating frequency, the output power can reach 45dBm, with a gain of 32dB.

[0137] If control module 2 selects the amplifier in maximum gain mode, the input signal passes through frequency discriminator module 1, resulting in a signal with a center frequency of 200.11MHz.
