Abstract
A circuit includes a first amplifier that first compares a ramp signal and a reset signal of a pixel signal output from a pixel array in a first operation period, second compares the ramp signal and an image signal of the pixel signal in a second operation period, and generates a first output signal in the first and second operation periods based on first and second comparison results; and a second amplifier that charges a capacitor in response to a second auto-zero signal in a second auto-zero period, stops an operation of the second amplifier from a time point at which the second auto-zero period ends to a time point at which the first operation period starts, and generates a second output signal based on the first output signal in the first operation period and the second operation period.
