摘　　要：单光子雪崩光电二极管(SPAD)是目前激光测距领域常见的单光子探测器。针对SPAD在单光子探测应用中的高速淬灭问题,设计了一种可以快速淬灭雪崩电流、缩短偏置电压恢复时间的主被动混合淬灭电路。根据实际使用的SPAD器件相关性能参数,建立了SPAD的SPICE模型;使用被动淬灭电路对该模型进行验证,证实了该模型的准确性和实用性;结合SPICE模型,通过计算机仿真技术对主被动混合淬灭电路进行了参数调整和功能验证。结果表明,所设计电路的淬灭时间和恢复时间分别达到200和400ps,满足单光子激光测距的应用需求。该混合淬灭电路结构简单,可以用于全集成单光子阵列探测器的相关研究。An mixed active-passive quenching circuit,which can quench the avalanche current and shorten the bias voltage recovery time quickly,was designed.A SPICE model was established for single photon avalanche diode detector（SPAD）,and the accuracy and practicability of the model was verified by using passive quenching circuit.Then parameter adjustment and functional verfication of the designed circuit were carried out by combining SPICE model and computer simulation technology.Simulation results show that the quenching time and recovery time of the circuit reaches 150 and 400 ps,respectively,which can meet the requirement of single photon laser ranging.
