Amorphous Silicon Single Photon Avalanche Diode Integrated with Memristor for Short Term Memory Based Rapid Passive Quenching

This paper presents a single stack structure integrating a Single Photon Avalanche Diode (SPAD) and a memristor, for rapid quenching and recharge using the short term memory of a memristor in its threshold switching behaviour. The fabricated device is compatible with typical CMOS process. It uses a circuit similar to passive quenching, typically used in single photon imaging devices. However, by using a memristor, it experimentally achieves performance similar to active reset operation without using additional circuitry and hence, at same pixel size and fill factor.
