Abstract: An analog-to-digital converter includes a gain amplification unit configured to receive a pixel signal at a first node and to amplify a gain of the pixel signal, a first capacitor connected between the first node and a second node, an amplifier configured to receive and amplify a signal output from the gain amplification unit and the first capacitor, and a conversion circuit configured to convert an output signal of the amplifier to a digital signal based on a reference signal and output the digital signal as a first output signal.
