Abstract
A comparator includes a first comparison block suitable for sampling a pixel signal, comparing a sampled pixel signal with a coarse ramping voltage, outputting a first comparison signal, sampling a coarse step voltage and outputting a residue voltage as a difference voltage between the sampled pixel signal and a sampled coarse step voltage; and a second comparison block suitable for comparing a fine ramping voltage with the residue voltage of the first comparison block and outputting a second comparison signal.
