Abstract:This paper addresses the development of a micropower 176 x 144 self-clocked CMOS active pixel image sensor that dissipates oneto-two orders of magnitude less power than current state of the art CMOS image sensors. The chip operates from a 1.5 V voltage source and the power consumption measured for the chip running from an internal 25.2 MHz clock yielding 30 frames per second is about 550 µW. This amount enables the sensor to be run from a watch battery. It is believed that this chip is the world's lowest power… Show more
