Document Type and Number:
Japanese Patent JPWO2020179696
Kind Code:
A1
Abstract:
A light receiving device according to an embodiment includes: a light receiving element (1000) in which a current flows because of avalanche multiplication caused in accordance with a photon that has been incident on the light receiving element in a state in which the light receiving element is charged to a predetermined potential based on a bias voltage, the light receiving element returning to said state by a recharge current; a detection unit (1002) configured to detect the current, and invert an output signal in a case in which a current value of the current exceeds a threshold; a current source (1001) configured to supply the recharge current to the light receiving element; and a switch unit (1010) configured to control supply of the bias voltage to the light receiving element in accordance with the output signal of the detection unit.
