Abstract: Disclosed is a circuit which includes a first amplifier that generates a first output signal by comparing a ramp signal and a reset signal of a pixel signal output from a pixel array in a first operating period and comparing the ramp signal and an image signal of the pixel signal output from the pixel array in a second operating period, a second amplifier that generates a second output signal based on the first output signal, and a counter. During at least one operating period of the first operating period and the second operating period, the first output signal controls a first source current of the first amplifier, or the second output signal controls at least one of the first source current of the first amplifier and a second source current of the second amplifier.

Abstract: An image sensor includes a pixel array in which a plurality of pixels, first and second row selection lines separated from each other, and first and second column lines separated from each other are disposed and a column selecting circuit configured to connect the first and second column lines using a column selection signal. The pixel array includes a first pixel which is connected to the first row selection line and the first column line and a second pixel which is disposed in the same row as the first pixel and connected to the second row selection line and the second column line.
