Single photon avalanche diode(SPAD) is an avalanche photodiode (APD) operating above its breakdown voltage,or what is called Geiger-mode.For the detection of very faint optical signals,for example,in application of early warning of hypersonic vehicles,SPAD may be an ideal choice.SPAD must operate in association with avalanche quenching circuits.Based on the equivalent circuit model of the pn junction,basic circuit configurations suitable for SPAD avalanche quenching,such as passive,active,and mixed quenching circuit,are analyzed.Passive quenching circuits,which are simple and useful for SPAD device testing and selection,have fairly limited application.Active quenching circuits make it possible to exploit the best performance of SPAD.Mixed solutions can be an effective approach to designing simple and compact circuits or for satisfying specific application requirements.General operating characteristics,recent progress,and the measures of performance of the SPAD quenching circuit are briefly reviewed in this paper.
