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 13):
A complementary metal oxide semiconductor (CMOS) image sensor comprising:\n a pixel array suitable for generating a pixel signal; a ramp signal generator suitable for generating coarse and fine ramping signals; a first comparison block suitable for generating a first comparison result signal by comparing the pixel signal to the coarse ramping signal, and for sampling a coarse step signal; a second comparison block suitable for generating a second comparison result signal by comparing the fine ramping signal to a difference between the coarse ramping signal and an accumulated difference between the pixel signal and the coarse step signal; a counter suitable for counting a clock according to the first and second comparison result signals; and a column read-out circuit suitable for outputting a count result of the counter, wherein the second comparison block is serially coupled to the first comparison block.
