Original Abstract Submitted
In some embodiments, a circuit includes a first amplifier, a second amplifier, and a counter. The first amplifier operates based on a first power supply voltage and generates a first output signal by comparing a ramp signal and a reset signal of a pixel signal output from a pixel array during a first operation period and comparing the ramp signal and an image signal of the pixel signal output from the pixel array during a second operation period. The second amplifier operates based on the first power supply voltage, generates a second output signal based on the first output signal and adjust a voltage level of the second output signal from a low level to a third level. The counter operates based on a second power supply voltage, counts pulses of the second output signal, and outputs a counting result as a digital signal.
