Pulse signal adjusting and amplifying circuit and method

The invention provides a pulse signal adjusting and amplifying circuit and method, and the circuit comprises a signal adjusting module and an amplifying module, the signal adjusting module is used for receiving an input signal, a positive phase adjusting voltage and a negative phase adjusting voltage, and carrying out the sampling of the pulse of the input signal, and obtaining a sampling signal; the positive-phase regulating voltage and the negative-phase regulating voltage are superposed on a sampling signal, a base line of the sampling signal is corrected to obtain a corrected signal, the corrected signal is filtered to obtain a regulating signal, and the amplifying module amplifies the regulating signal to obtain an output signal. According to the invention, sampling, baseline adjustment and filtering are carried out on the input signal through the signal adjustment module to obtain the adjustment signal, and the adjustment signal is amplified and output, so that the waveform of the output signal is stabl
