Abstract
Power consumption is reduced in a solid-state imaging element that amplifies a voltage for each column. The solid-state imaging element includes a pixel circuit, an input transistor, a reference side current source, and a feedback circuit. The pixel circuit generates an input voltage by photoelectric conversion. The input transistor outputs an output voltage depending on a voltage between a source to which the input voltage is input and a gate from a drain. The reference side current source is connected to a reference node at a predetermined reference voltage and supplies a predetermined current. The feedback circuit feeds back a part of the current to the gate of the input transistor.
