Abstract
A comparing circuit may include a first amplifier and a second amplifier. The first amplifier performs a correlated double sampling operation in response to a pixel signal and a ramp signal, and the second amplifier amplifies an output signal of the first amplifier. The second amplifier includes a current stabilization circuit that supplies current to the second amplifier during the correlated double sampling operation irrespective of the output signal of the first amplifier.
