Abstract

Disclosed is a differential chopper comparator, which includes an input terminal circuit that receives a first input signal and a second input signal and selectively switches the first and second input signals to intermediate circuit, at least one chopper circuit that generates a first amplified signal and a second amplified signal by amplifying a difference between the first and second input signals at the intermediate circuit points, a comparison circuit that compares the first amplified signal with the second amplified signal, digitizes the comparison result, and outputs a digital signal at a logic level, and a compensation circuit that offsets the first amplified signal and the second amplified signal and thereby removes kickback noise induced in the input terminal circuit. The differential chopper comparator of the present disclosure may shorten the settling time and may operate at high speed.
