ABSTRACT:
A technique for operating a source follower buffer circuit, such as employed in a charge domain pipeline, to eliminate floating diffusion signal charge contamination from downstream circuits. The method and apparatus places an output of the circuit in a known state immediately prior to charge transfer into a floating diffusion, and again in known state immediately prior to charge transfer out of the floating diffusion.
