摘要（英）：

The invention provides a quenching resetting circuit of a single photon avalanche diode. The circuit comprises the single photon avalanche diode, a passive resetting module, a quenching module, and an active resetting module, the passive resetting module is used for resetting an anode of the single photon avalanche diode to a low potential through external resetting signals, the quenching module is used for reducing a reverse bias voltage of the single photon avalanche diode to be below a critical avalanche voltage after avalanche of the single photon avalanche diode, and the active resetting module is used for resetting the anode of the single photon avalanche diode to the low potential after quenching is finished. According to the circuit, the damage to devices by high current generated by avalanche can be avoided, the condition of oscillation of signal nodes is effectively improved, the circuit is prevented from entering an erroneous state, the work performance of the quenching resetting circuit of the single photon avalanche diode is greatly enhanced, and the practicality and the operationality of the quenching resetting circuit of the single photon avalanche diode in the practical usage are optimized.
