Abstract :
CMOS active pixel sensors (APS) have attracted special attention in recent years because of monolithic integration of controlling, driving and signal processing circuitry within a single sensor chip. However, a large pixel area is required for implementing row select, charge reset and amplification elements in a pixel. Further pixel size shrinkage is necessary, especially for applications like consumer-use digital still photography. Reduced cell size is reported for the television, but the device operates only in the interlace scan mode. This consumer-use 1/4 inch 640(H)x480(V) pixel active pixel sensor has a 5.6x5.6/spl mu/m/sup 2/ pixel. The imager operates with a 5.0V single power supply and less than 30mW dissipation. The sensor uses 0.6/spl mu/m, double poly-silicon, triple-metal CMOS process technology.
