摘要: The optimization of two technologies (CMOS and CCD) wherein a pinned photodiode is integrated into the image sensing element an active pixel sensor. Pinned photodiodes are fabricated with CCD process steps architecture. Charge within transferred charge node by transfer gate. floating diffusion coupled CMOS circuitry that can provide addressing capabilities individual pixels. Alternatively, buried channel photocapacitor be used in place photodiode.
