Abstract :
A CMOS image sensor codenamed EYE2, developed on a standard Intel CMOS process and designed into the Intel 971 Camera Kit, is described. EYE2 converted incident visual images into 10-bit digital data streams for still and video imaging applications. The analog signal processing that is essential to achieving the very high SNR desired is detailed. A fully differential architecture was implemented in order to achieve a desired SNR of 60 dB with known techniques for the minimization of signal degradation. The novel techniques implemented helped to speed up the analog signal path and reduced power consumption in the chip
