Abstract:
A comparator includes a first amplification unit suitable for differentially amplifying a pixel signal and a ramp signal, a second amplification unit suitable for amplifying a signal outputted from the first amplification unit and outputting a comparison result, a current control unit suitable for controlling a current flow in response to the comparison result and a current compensation and noise removal unit suitable for compensating for current and removing noise under control of the current control unit.
