A novel active quenching circuit for single photon detection with Geiger mode avalanche photodiodes
, 2008 In this paper we present a novel construction of an active quenching circuit intended for single photon detection. For purpose of evaluation, we have combined this circuit with a standard avalanche photodiode C30902S to form a single photon detector.
