2015 Symposium on VLSI Circuits (VLSI Circuits), 2015•ieeexplore.ieee.orgA 0.4 V self-powered 96× 96-pixel PWM imager is proposed and prototyped in standard 0.18
μm CMOS technology. A dual-exposure extended-counting (DEEC) PWM sensor is
developed to achieve a 140dB dynamic range with a boost of 53dB. The chip consumes
12.1 μW at 12fps and 38.4 μW at 60fps, results in an iFoM of 53.7 and 33.9 fJ/pixel. code,
respectively. Optical energy harvesting (OEH) mode is implemented to generate 459mV and
3.21 μW at 100klux (sunny day) and achieve a self-powered imaging at 15fps.
