Systems such as digital still cameras, robots, etc. require low-cost, low-power and high-resolution. This CMOS image sensor has reduced cell size. The sensor is fabricated using 0.6 /spl mu/m, triple-poly-silicon, double-metal CMOS process technology. The sensor has 3.7/spl times/3.7 /spl mu/m/sup 2/ pixels. It operates with one 3.3V power supply and has less than 30mW power dissipation.
