Individual single-photon avalanche diodes (SPADs) have long been the detector of choice when deep sub-nanosecond timing performance is required, due to their excellent single-photon detection and time-stamping capability1,2,3,4. The breakthrough implementation of the first SPADs in standard complemen...
A CMOS single photon avalanche diode (SPAD) design uses conventional, or at least known, CMOS processes to produce a device having a breakdown region in which the main p-n junction is formed of a deep n-well layer, and optionally on the other side, a p-add layer. The SPAD may also ...

In this paper we present a comprehensive circuit model for single photon avalanche diodes (SPADs), implemented into two different CAD circuit simulation environments (PSpice and Spectre), that fully describes detector behavior in the above-breakdown (Geiger-mode) operation. In particular, the SPICE ...
