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.

Abstract: An image sensor and an image processing system. The image sensor includes a pixel array comprising a plurality of pixels, a row driver configured to generate control signals for controlling the plurality of pixels, the row driver configured to use an external voltage received from a source outside the image sensor and an internal voltage generated within the image sensor, and a voltage generator configured to generate the internal voltage, wherein the external voltage includes a first external voltage and a second external voltage, the internal voltage includes a first internal voltage and a second internal voltage, a level of the first internal voltage is higher than a level of the second internal voltage, and a level of the first external voltage is between the level of the first internal voltage and the level of the second internal voltage.
