Abstract
In an integrated-circuit image sensor having a pixel array, first and second control pulses that enable photocharge transfer from respective first and second photosensitive elements to a shared floating diffusion node are staggered in time such that capacitive feedthrough to the shared floating diffusion node from a trailing edge of the first control pulse is counteracted by capacitive feedthrough to the shared floating diffusion node from a leading edge of the second control pulse.
