Abstract
In this paper, we propose an analog pixel differencing circuit for differentiating pixels between frames directly from CMOS pixels. The analog information processing at sensor is a topic of growing appeal to develop edge AI devices. The proposed circuit is integrated into a pixel-parallel and pixel-column architectures. The proposed system is design using TSMC 180nm CMOS technology. The power dissipation of the proposed circuit is 96.64mW, and on-chip ares is 531.66/mu m(2). The architectures are tested for moving object detection application.
