Solid-state imaging element and imaging apparatus

Abstract

The technology of the present disclosure improves an image quality in a solid-state imaging element that amplifies a voltage for every column. In the solid-state imaging element, an input transistor outputs, from a drain, an output voltage corresponding to a voltage between a source and a gate to which an input voltage is input. A base side current source transistor supplies a predetermined current from the drain of the input transistor to a base node determined in advance. A feedback circuit feeds back a part of the predetermined current to the gate of the input transistor. The clamp circuit limits the output voltage to a value higher than a lower limit voltage determined in advance.
