Abstract
To improve a frame rate in a solid-state imaging element that compares a reference signal and a pixel signal. The solid-state imaging element includes a differential amplifier circuit, a transfer transistor, and a source follower circuit. The differential amplifier circuit amplifies a difference between the potentials of a pair of input nodes and outputs the difference from an output node. The transfer transistor transfers charge from a photoelectric conversion element to a floating diffusion layer. The auto-zero transistor short-circuits the floating diffusion layer and the output node in a predetermined period. The source follower circuit supplies a potential to one of the pair of input nodes according to a potential of the floating diffusion layer.
