Abstract
A fully depleted photodiode accumulates charge into both the diode and a separate floating diffusion. The floating diffusion has less capacitance that the overall diode, thereby resulting in a knee-shaped transfer characteristic for charge accumulation. The fully depleted photodiode also include two PN junctions, one near the surface and the other buried below the surface.
