Abstract

This paper reports on a redesign of an event pixel by frame differencing with a lateral overflow capacitor for dynamic range extension. In the first prototype, the inclusion of an inpixel correlated double sampling (CDS) and an algorithm for dynamic range extension resulted in a large pixel area, with a 32μm pitch in 180 nm CMOS technology. This paper studies a CDS free version of our former pixel through post-layout simulations. The pixel pitch is shrinked to 22μm, power consumption is lowered and speed is preserved.
