N2 - This paper introduces a digital dynamic vision sensor (DVS) with single-photon avalanche diode (SPAD). The sensor operates in a fully digital manner, eliminating circuit noise and non-uniformity. To provide a motion-adaptive optimum frame rate and minimize vibration-event noise (VEN) caused by sensor vibrations, the sensor generates multiple events via quantized delta (QD) signal. Thanks to the QD, the sensor detects the relative speed of moving objects, adjust the frame rate accordingly, and filter out VEN, thereby allowing only essential events from the objects. Furthermore, the sensor incorporates event-driven threshold control (EDTC) logic to ensure the optimal number of events. The EDTC and VEN filter offers data reduction of 72.8% and 64.5%, respectively.
