Abstract:
Digital cameras have far surpassed film cameras. CMOS technology, with the pinned-photodiode architecture rivals CCDs for image quality, with benefits of large-scale integration with signal processing for complete camera-on-a-chip systems. In this talk I will discuss the signal path from incident photons to captured electrons (quantum efficiency) and noise including electronic, statistical and color-space conversion based sources. Photoelectron capture and channel crosstalk in particular will be discussed with emphasis on numerical modeling of electron transport in the silicon photodiode region.
