Enhancing Dynamic Vision Sensors Performance with a Photovoltaic Receptor

We introduce a Dynamic Vision Sensor (DVS) with a unique pixel architecture. Unlike conventional designs, the proposed architecture substitutes the photoreceptor front-end with a single diode operating in photovoltaic regime. Acting as a solar cell, this diode provides competitive sensitivity to transient illumination changes, especially in low-light settings, thanks to its self-biased condition and signal-noise ratio. This design offers compactness compared to logarithmic photorecep-tors. Additionally, it showcases highly competitive latency and noise performance.
