Abstract
A sensor includes an avalanche photodiode (APD), a first resistor, a second resistor, and a rectification element. The first resistor is connected between a current output terminal of the APD and a first output terminal. The second resistor and the rectification element are connected in series between the current output terminal and a second output terminal. The rectification element is connected between the second resistor and the second output terminal.
