Abstract
The present technology relates to a light receiving element and a ranging system to reduce power consumption. A light receiving element includes a pixel which includes an SPAD, a first transistor configured to set a cathode voltage of the SPAD at a first negative voltage, a voltage conversion circuit configured to convert the cathode voltage of the SPAD upon incidence of a photon and output the converted cathode voltage, and an output unit configured to output a detection signal indicating the incidence of the photon on the SPAD on the basis of the converted cathode voltage. The present technology is applicable to a ranging system that detects a range in a depth direction to a subject, for example.
