• abstract: We report on the noise performance of a color CMOS photogate image sensor that supports two levels of correlated double sampling and has high conversion gain at each pixel. Imager performance is limited by low quantum efficiency and dark current non-uniformity and not by read-out circuit temporal or fixed-pattern noise.
