Standard CMOS active pixel image sensors for multimedia applications

The task of image acquisition is completely dominated by CCD-based sensors fabricated on
specialized process lines. These devices provide an essentially passive means of detecting
photons and moving image data across chip. We argue that line widths in standard CMOS
have been reduced to the point where it is practical to locate transistors-and hence provide
gain-within each detector of an imager fabricated in CMOS. In this paper we describe the
image sensors we have been building in this technology. They use far less power, permit …
