Title:
SOLID-STATE IMAGING DEVICE AND CAMERA
Document Type and Number:
WIPO Patent Application WO/2020/261746
Kind Code:
A1
Abstract:
This solid-state imaging device comprises: a pixel unit that outputs a pixel signal corresponding to the amount of incident light; an A/D conversion unit that A/D-converts the pixel signal; and a D/A conversion circuit that generates a reference signal used in the A/D conversion unit, wherein the D/A conversion circuit includes a first buffer circuit that outputs a reference voltage VTOP for generating the reference signal, and the first buffer circuit includes a differential pair circuit having a first transistor and a second transistor, and a suppression circuit that suppresses a variation in the reference voltage by offsetting a difference in characteristics between the first transistor and the second transistor.
