Abstract
Provided is a control circuit and a distance measurement system. The control circuit includes first wiring to which a first power supply voltage is applied, second wiring to which a second power supply voltage is applied. The control circuit further includes a current supply unit, a first withstand voltage unit, an inverter connected to a cathode of the SPAD element, and a second withstand voltage unit. Furthermore, the control circuit includes an N-type first transistor that is provided between the cathode of the SPAD element and an input terminal of the inverter, and has a gate connected to the second wiring, and a P-type second transistor that is provided between the second wiring and a source of the first transistor, and has a gate connected to an output terminal of the inverter.
