摘要： A method (100) for processing an analog signal is provided. The method comprises the steps of modulating (101) the analog signal using a chopping signal with a chopping frequency fchop to generate a modulated signal, amplifying (102) the modulated signal to generate an amplified signal, low-pass filtering (103) the amplified signal to generate a filtered signal comprising at least one harmonic of the modulated signal, and sub-sampling (104) the filtered signal and performing correlated double sampling operation by subtracting the samples at the chopping frequency.
