The present invention discloses a signal analysis circuit and a signal analysis method. The signal analysis circuit comprises a peak value detector, a subtraction amplifying unit and a comparison unit. The peak value detector is used for capturing the peak value of a first voltage signal so as to generate a second voltage signal. The subtraction amplifying unit is used for generating a comparison voltage signal according to the second voltage signal and is used for amplifying the difference between the voltage values of the second voltage signal and the comparison voltage signal so as to generate a third voltage signal. The peak-to-peak value of the third voltage signal is larger than that of the second voltage signal. The comparison unit is used for comparing the voltage values of the third voltage signal and the comparison voltage signal so as to generate an output voltage signal. In this way, a signal analysis circuit can be realized. 本发明公开了种信号解析电路及信号解析方法。信号解析电路包括峰值检测器、减法放大单元以及比较单元。峰值检测器，用以撷取第电压信号的峰值，以产生第二
