Abstract
A photoelectric conversion device includes an avalanche photodiode including a first terminal and a second terminal, a first power supply connected to the first terminal, a second power supply connected to the second terminal, and a switch for switching a resistance value between the first power supply and the first terminal. The first terminal of the avalanche photodiode is connected to each of a gate of a first p-channel metal-oxide semiconductor (PMOS) transistor and a gate of a first n-channel MOS (NMOS) transistor, the first PMOS transistor and the first NMOS transistor being connected in series between a third and a fourth power supplies. The photoelectric conversion device further includes a first cut-off unit for cutting off an electrical path between the third power supply and the fourth power supply, and if the switch is controlled to a standby state, the first cut-off unit cuts off the electrical path.
