摘要: This paper addresses the development of a micropower 176/spl times/144 CMOS active pixel image sensor that dissipates one to two orders magnitude less power than current state-of-the-art sensors. The chip operates from 1.5-V voltage source and consumption measured for running an internal 25.2-MHz clock yielding 30 frames per second is about 550 /spl mu/W. amount enables run watch battery. In order achieve design goals, low-power methodology applied throughout process system-level process-level, while realizing performance satisfy specification. As autonomous sensor, it can be operated with only three pads [GND, VDD (1.2-1.7 V), DATAOUT]. die occupies 4 mm/sup 2/ silicon.
