Abstract
A pixel circuit within an integrated-circuit image sensor includes a photodiode having a pinning layer of a first conductivity type, a floating diffusion node and a transfer gate disposed between the photodiode and the floating diffusion node. A first control input is coupled to the transfer gate, and a second control input is coupled to the pinning layer of the photodiode to enable the depletion potential of the photodiode to be raised and lowered.
