• abstract: A simple and robust self-reset pixel-level CMOS image sensor (CIS) has been designed and tested to verify the improvement of the signal-to-noise ratio (SNR) compare to the conventional asynchronous self-reset pixel-level CISs. It significantly reduces noise accumulation from multiple self-resets by replacing a comparator and redundant regenerative modules with a simple Schmitt trigger circuit.
