Abstract
A signal analysis circuit and a signal analysis method thereof are disclosed. The signal analysis circuit includes a peak detector, a subtraction amplifying unit, and a compare unit. The peak detector obtains a peak value of a first voltage signal to generate a second voltage signal. The subtraction amplifying unit generates a compare voltage signal according to the second voltage signal, and amplifies a voltage value difference between the second voltage signal and the compare voltage signal to generate a third voltage signal. A peak-to-peak value of the third voltage signal is larger than a peak-to-peak value of the second voltage signal. The compare unit compares the voltage value of the third voltage signal and the voltage value of the compare voltage signal to generate an output voltage signal. In such a manner, a new signal analysis circuit can be realized.
