Abstract
A sigma-delta analog-to-digital converter includes an integrator and a dither signal generator for generating a digital dither signal, and a plurality of comparators for converting an analog signal received from the integrator into an output digital value. A digital logic unit is in data communication with the digital dither signal and the comparators. The digital logic unit is configured to change the output digital value on the basis of the digital dither signal.
