December 16, 2014, IEDM, San Francisco—Edoardo Charbon from Delft University of Technology presented a paper on SPAD photo-detectors. Changes in device topology and processing help improve performance while reducing parametric variations. The basic operating mode for the detector is to have a charge build-up cycle, followed by a quench upon detection, then a recharge. The…
