Abstract
Disclosed is a circuit which includes a first amplifier that generates a first output signal by comparing a first pixel signal corresponding to a first conversion gain and a first ramp signal and generates a second output signal by comparing a second pixel signal corresponding to a second conversion gain and a second ramp signal, and a second amplifier that generates a third output signal based on the first output signal and generates a fourth output signal based on the second output signal, the first conversion gain is higher than the second conversion gain, and a first power current of the first amplifier when the first pixel signal and the first ramp signal are compared is different from a second power current of the first amplifier when the second pixel signal and the second ramp signal are compared.
