Abstract
A correlated double sampling circuit includes a delta-sigma modulator, a selection circuit, and an accumulation circuit. The delta-sigma modulator is configured to receive an input signal, delta-sigma modulate the input signal, and output a modulation signal. The selection circuit is configured to invert the modulation signal and selectively output one of the modulation signal and an inverted modulation signal in response to a selection signal corresponding to an operation phase. The accumulation circuit is configured to generate a first accumulation result by performing an accumulation process on one of the modulation signal and the inverted modulation signal in a first operation phase, and generate a second accumulation result by performing the accumulation process on the first accumulation result and the other one of the modulation signal and the inverted modulation signal in a second operation phase.
