摘　　要：在SPAD等效电路的基础上建立了简单实用的SPICE电路模型,并对SPAD四种基本的工作电路结构(被动淬灭、主动淬灭、门控模式和电容淬灭)进行了细致的仿真分析。仿真结果清晰的反映了四种电路各自的特性和优缺点,以及SPAD器件寄生参数对于电路性能的影响,得到了与实验基本一致结果。该电路模型可以直接应用于后续信号读出电路及前置放大电路系统的仿真设计,调节电路参数,优化电路性能,从而节省后续电路设计与制作的时间。Based on the equivalent circuit of a SPAD, we have established a simple and useful SPICE circuit model and done some simulations on four basic working circuit structures of SPAD （i. e. passive quenching, active quenching, gated mode and capacitive quenching）. The simulation results, which are consistent with experiments, show their different characteristics clearly as well as the SPAD parameters＇ effects to its performance. It＇s helpful in SPAD device optimized design and its subsequent electronic circuits and applications.
