A CMOS image sensor with dark-current cancellation and dynamic sensitivity operations.

A CMOS image sensor with dark-current cancellation and dynamic sensitivity operations.

An ultralow dark-signal and high-sensitivity pixel has been developed for an embedded active-pixel CMOS image sensor by using a standard 0.35-μm CMOS logic process. To achieve in-pixel dark-current cancellation, we developed a combined photogate/photodiode photon-sensing device with a novel operatio...
