Title:
SOLID-STATE IMAGING ELEMENT AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/003980
Kind Code:
A1
Abstract:
Provided is a solid-state imaging device with which it is possible to improve the dynamic range of an ADC and thereby improve imaging characteristics. Provided is a solid-state imaging element (11) comprising a pixel array (12) having a plurality of pixels for outputting a pixel signal by photoelectric conversion, and an AD conversion processing unit (30) for executing AD conversion on the pixel signal, the AD conversion processing unit comprising a comparator (31) that has: a first amplification unit (81) having a pair of first differential pairs comprising a P-type transistor and a pair of second differential pairs comprising an N-type transistor; and a second amplification unit (82) in which a P-type and an N-type transistor are connected in series, the second amplification unit amplifying the output of the first amplification unit.
