摘要
A comparator includes a first comparison block suitable for accumulating a difference value between a voltage of a pixel signal and a coarse step voltage, and outputting a residue voltage, representing a difference between a coarse ramping voltage of a ramp signal and the accumulated difference value; and a second comparison block suitable for comparing a fine ramping voltage to the residue voltage of the first comparison block and outputting a third comparison result signal.
