Solid-state imaging device, method for driving solid-state imaging device, and electronic apparatus

Abstract

Provided are a solid-state imaging device, a method for driving a solid-state imaging device and an electronic apparatus that are capable of achieving reduced noise at a voltage sample-and-hold node without requiring an increase in capacitance of a signal holding capacitor for sampling and holding voltage. A solid-state imaging device includes: a photoelectric conversion reading part; an amplifier circuit; a signal holding part including a sample-and-hold signal holding capacitor for holding the read-out voltage signal amplified by the amplifier circuit and outputting the held voltage signal; a first in-pixel signal line to which a low-gain read-out voltage signal is output; and a second in-pixel signal line connected to the output side of the amplifier circuit and to which a high-gain read-out voltage signal is output. A second differential transistor of a differential transistor pair of the amplifier circuit also serves as a source follower transistor.
