Abstract
A comparator circuit of an image sensor that is configured to compare a pixel signal and a ramp signal is introduced. The comparator circuit includes a first comparator circuit and a second comparator circuit. The first comparator circuit includes differential inputs that receive the pixel signal and the ramp signal, respectively. The second comparator circuit includes differential inputs that receive the pixel signal and the ramp signal, respectively. The second comparator circuit is activated when a level of the pixel signal is smaller than a first threshold value, the first comparator circuit is activated when the level of the pixel signal is greater than a second threshold value, and the first threshold value is greater than the second threshold value.
