An accurate and complete circuit simulation model for single-photon avalanche diodes(SPADs) is presented.The derived model is not only able to simulate the static DC and dynamic AC behaviors of an SPAD operating in Geiger-mode,but also can emulate the second breakdown and the forward bias behaviors.In particular,it considers important statistical effects,such as dark-counting and after-pulsing phenomena.The developed model is implemented using the Verilog-A description language and can be directly performed in commercial simulators such as Cadence Spectre.The Spectre simulation results give a very good agreement with the experimental results reported in the open literature.This model shows a high simulation accuracy and very fast simulation rate.
