Abstract

The invention discloses a stable signal amplifying circuit structure; it solves the problem of low versatility of the impedance amplifier caused by the difficulty in adjusting the impedance of the impedance amplifier in the prior art; it includes a VCC, a current mirror, a first acquisition circuit, a second acquisition circuit, a control module, and an impedance amplifier. An adjustment module, the control module enables the current mirror to receive gradient equivalent impedance by selectively opening the impedance adjustment unit, and the current mirror outputs an amplified voltage; The output control signal voltage value of the module can adjust the impedance in the circuit to adjust the output of the current mirror, and realize the signal gradient amplification of the circuit.

Description

technical field [0001] The invention relates to the field of impedance amplifiers, in particular to a stable signal amplifying circuit structure. Background technique [0002] In the field of electronic technology, after the signal is collected, it cannot be directly processed by the CPU, and the collected signal needs to be converted to meet the processing requirements of the CPU. At present, in the acquisition process of the frequency converter signal, the existing signal acquisition circuit only has the function of conversion, and cannot guarantee the stability and accuracy of the conversion, and the output signal may also have deviations. In addition, the signal of some frequency converters is susceptible to interference, which is not conducive to the processing of the signal. [0003] An amplifier is a device that can amplify the voltage or power of an input signal and consists of a tube or transistor, a power transformer and other electrical components. Used in vario...
