SOLID-STATE IMAGE CAPTURING ELEMENT, AND ELECTRONIC DEVICE

Title:

SOLID-STATE IMAGE CAPTURING ELEMENT, AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2018/131510

Kind Code:

A1

Abstract:

This disclosure relates to a solid-state image capturing element and an electronic device which enable a time width of a pulse signal to be adequately ensured. In an AD converter for each unit pixel, a pulse generating circuit causes a delayed signal obtained by delaying an output signal from a comparator to be returned to the comparator, and generates a pulse signal by computing the output signal and the delayed signal. A latch circuit latches the pulse signals generated by the pulse generating circuit. The present disclosure can be applied to stacked-type backside illumination type solid-state image capturing elements, for example.
