Single-photon detection by avalanche photodiodes with uniform breakdown over the junction area (single--photon avalanche diodes SPADs) is well known. The active quenching method, introduced by the ...

Abstract: The intensive development of Single-photon avalanche photodiode (SPAD) based CMOS image sensors (CIS) continues, with rapid progress [1-6]. Yet, due to unestablished quenching operation [5,6 ...
