Abstract
A comparator circuit is disclosed. The comparator circuit includes a comparator with a first input terminal configured to receive a first input signal, a second input terminal configured to receive a second input signal, a chopper circuit configured to alternate an input polarity of an input stage during a first phase and a second phase. The comparator circuit further includes a counter circuit coupled to receive a comparator-output signal and a clock signal, the counter circuit configured to generate a first count during the first phase and to generate a second count during the second phase based on the comparator-output signal and the clock signal. The comparator circuit further includes a compensation circuit configured to generate an offset-compensation signal based on the first count and the second count. The comparator further includes an offset controller configured to adjust an input offset of the comparator based on the offset-compensation signal.
