Title:

SOLID-STATE IMAGING DEVICE, COMPARATOR AND ELECTRONIC EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2024/070740

Kind Code:

A1

Abstract:

[Problem] To reduce noise in an image sensor. [Solution] This solid-state imaging device comprises a light receiving element, a first amplification circuit, a second amplification circuit and a control circuit. The first amplification circuit amplifies and outputs the difference between a reference signal and an input signal outputted from the light receiving element. The second amplification circuit amplifies and outputs the first amplified signal outputted by the first amplification circuit. The control circuit controls, on the basis of the reference signal, an active load of the first amplification circuit or the mutual conductance of at least one of amplification transistors of the second amplification circuit.
