Title:
LIGHT RECEIVING ELEMENT AND DISTANCE MEASURING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/045123
Kind Code:
A1
Abstract:
The present technology relates to a light receiving element and a distance measuring system, wherein power consumption can be reduced. The light receiving element comprises a pixel including: a SPAD; a first transistor that sets a cathode voltage of the SPAD to a first negative voltage; a voltage conversion circuit that converts and outputs the cathode voltage of the SPAD when a photon is incident; and an output unit that outputs a detection signal indicating the incidence of a photon onto the SPAD on the basis of the converted cathode voltage. The present technology can be applied to, for example, a distance measuring system that detects a distance in a depth direction to a subject.
