摘要：
This paper describes a motion-triggered CMOS image sensor. It uses low resolution photosensor array with an ultra low power data converter in the readout circuit. The analog motion sensor shares the same photosensors using an interleaved structure. The motion sensor triggers the digital imager and RF data transmission to the base station in case there are objects moving in the scene, otherwise, the system remains standby to save power. This design is specially optimized for very low power applications such as distributed wireless sensor network.
