A 60 mW 10 b CMOS image sensor with column-to-column FPN reduction

A 60 mW 10b 660(H)/spl times/490(v) pixel digital CMOS image sensor with column-to-column FPN reduction introduces the double inverting amplifier with double clamp circuit for reduction of column-to-column fixed pattern noise (dark FPN and light FPN). It operates with a 3.3 V power supply and has 60 mW power consumption. This sensor is uses 0.6 /spl mu/m, triple-poly-silicon, double-metal CMOS technology.
