Abstract
An amplifier transistor within an image-sensor pixel is implemented upside down relative to conventional orientation such that a substrate-resident floating diffusion node of the pixel forms the gate of the amplifier transistor—achieving increased pixel conversion gain by eliminating the conventional metal-layer interconnection between the floating diffusion node and amplifier-transistor gate and concomitant parasitic capacitance.
