Abstract :
This paper presents a novel CMOS active pixel sensor (APS) imager with fully digital global readout channel and continuous time on-chip energy harvesting. Imager captures low-noise images while consuming 140nW of power at 0.7 FPS. Imager has a 0.078% total FPN in dark. It generates 31μW power at bright daylight.
