CONTROL CIRCUIT AND RANGING SYSTEM

The control circuit according to the present disclosure includes a passive circuit (10) and an active circuit (20). The passive circuit (10) is configured to: supply current to a Single Photon Avalanche Diode (SPAD) element (6a) from a supply path (Rp); and output a first pulse signal (P1) according to a signal generated in the SPAD element (6a). The active circuit (20) is configured to: supply current to the SPAD element (6a) selectively from among a plurality of supply paths; and output a second pulse signal (P2) according to a signal generated in the SPAD element (6a).
