Abstract

A method for generating chopper-stabilized signals includes the following steps. First, a voltage polarity control signal is received. Next, the voltage polarity control signal is sampled to obtain a sampling signal, and a voltage transformation manner of the voltage polarity inversion of the voltage polarity control signal is judged according to the sampling signal. Then, a frame transformation signal template is obtained according to the voltage transformation manner of the voltage polarity inversion of the voltage polarity control signal and the sampling signal. Next, the frame transformation signal template is compared with the sampling signal and a frame transformation signal is generated. Then, a first chopper-stabilized signal is outputted according to the frame transformation signal and the voltage polarity control signal.
