Solid-state imaging device

摘要

A pixel unit included in a sensor chip includes: a first pixel connected to a first feedback amplifier which is connected to a first column signal line as an input line and a first reset drain line as an output line; and a second pixel connected to a second feedback amplifier which is connected to a second column signal line as an input line and a second reset drain line as an output line. A drain of a reset transistor of the first pixel is connected to the first reset drain line, a drain of a reset transistor of the second pixel is connected to the second reset drain line, a source of an amplifying transistor of the first pixel is connected to the first column signal line, and a source of an amplifying transistor of the second pixel is connected to the second column signal line.
