Abstract:
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.

Claim (Index 4):
The comparator of  claim 1 , wherein the first comparison block includes:\n a first switch suitable for switching on or off the pixel signal; a first capacitor suitable for sampling the pixel signal inputted through the first switch; a second switch coupled between the first switch and a first ground terminal; a third switch coupled between a negative input node of the first comparator and the first ground terminal; a fourth switch coupled between the negative input node of the first comparator and an output node of the first comparator; a second capacitor coupled between the negative input node of the first comparator and the output node of the first comparator and suitable for sampling the accumulated difference value; a fifth switch suitable for switching on or off the coarse ramping voltage; a third capacitor coupled to the fifth switch and suitable for sampling the coarse step voltage; a sixth switch coupled between the third capacitor and a second ground terminal; and a first comparator suitable for comparing the sampled pixel signal of the first capacitor to the coarse ramping voltage applied through the fifth switch, outputting the first comparison result signal, comparing the coarse ramping voltage applied through the fifth switch to the accumulated difference value, outputting a second comparison result signal, and outputting the residue voltage.
