Abstract

A light detecting device includes first pixel circuitry including a first avalanche photodiode, and second pixel circuitry including a second avalanche photodiode, a first delay circuit including an input coupled to a cathode of the second avalanche photodiode, a first circuit including a first input coupled to the cathode of the second avalanche photodiode, and a second input coupled to an output of the first delay circuit. The light detecting device includes a control circuit coupled to an output of the first circuit and configured to control a potential of an anode of the first avalanche photodiode based on the output of the first circuit. The control circuit is configured to control a potential of an anode of the second avalanche photodiode based on the output of the first circuit.
