Abstract
A sigma-delta analog-to-digital converter is configured to convert an analog input signal to a digital output signal at a sampling frequency (f). The sigma-delta analog-to-digital converter includes a chopper circuit configured to shift the analog input signal from an original frequency to a chopper frequency (f=f/N) to generate a chopped analog signal, where N is a positive integer with N≥1. A chopper period includes a first chopper phase and a second chopper phase. The sigma-delta analog-to-digital converter also includes a timing circuit configured to adjust at least one of a duration of the first chopper phase or a duration of the second chopper phases according to (N/2−k)·T, with k being an odd integer equal to or larger than 1, and Tbeing a sampling period 1/fof the sigma-delta analog-to-digital converter.
