Abstract

A light receiving element and a ranging system is provided which achieve improvement of pixel characteristics while allowing variation in a breakdown voltage of an SPAD. The light receiving element includes a pixel array in which a plurality of pixels is arranged in a matrix, and a pixel driving unit configured to control respective pixels of the pixel array to be active pixels or non-active pixels. The pixel includes an SPAD, a transistor connected to the SPAD in series, an inverter configured to output a detection signal indicating incidence of a photon on the SPAD, a first transistor which is switched on or off in accordance with control of the pixels to be the active pixels or the non-active pixels, and a second transistor connected to the first transistor in series.
