Signal calibration circuit and signal calibration device

Abstract

A signal calibration circuit and a signal calibration method are provided. The signal calibration circuit includes: an analog-to-digital conversion circuit, coupled to an output terminal of the circuit to be tested, obtaining an analog signal output by the circuit to be tested and transforming the analog signal into a digital signal; a calibration signal generation circuit, generating a calibration signal, modifying the calibration signal according to a first signal, and outputting a modified calibration signal; and a calibration circuit, coupled to the analog-to-digital conversion circuit and the calibration signal generation circuit, obtaining the digital signal and the calibration signal, calibrating the digital signal according to the modified calibration signal and outputting a calibrated digital signal. The first signal is a predetermined signal or the calibrated digital signal output by the calibration circuit.
