A 30 frames/s SXGA 5.6 /spl mu/m pinned photodiode pixel column parallel CMOS image sensor achieves 340 /spl mu/V noise floor and 40 pA/cm/sup 2/ dark current. Performance is limited by pixel 1/f noise, not by the ADC noise floor of 140 /spl mu/V. The column ADC memory employs a custom DRAM to save area. The sensor utilizes a 0.35 /spl mu/m 1P 3M CMOS process.
