Abstract
A circuit includes a comparator including a first input, a second input, and an output. The circuit further includes a plurality of capacitive sampling circuits configured to be selectively coupled to the first and second inputs. Each of the plurality of capacitive sampling circuits includes first and second capacitors, and includes first and second conversion switches configured to selectively couple the first and second capacitors to the first and second inputs, respectively. The first and second conversion switches of a selected one of the plurality of capacitive sampling circuits are closed to couple the selected one to the first and second inputs of the comparator during a conversion phase.
