APDs for the FT region Avalanchephotodiodes in standard CMOS technologies Learningfromthefabricatedstructures: STM 130nm, AMS 0.35um Detector instabilities (dark counts, afterpulsing, cross-talk) are instabilities contributing to the detector response. Have deep impact on the readout details. It is very important to understand their origin and to reduce their incidence. Tryingtolearnalsofromdevicesimulations Design of pixels and readoutstructures: Active quenching and fastreadout.
