WebSep 17, 2024 · Dark current of a CMOS pixel is mainly generated as leakage current from the reverse biased photodiode and parasitic junctions. As discussed in [ 1 ], dark current is detrimental to imaging performance under low illumination as it introduces shot noise that cannot be corrected for as well as nonuniformity due to its large variation over the ... WebFeb 6, 2024 · A characteristic of photodiodes is that under reverse bias conditions (photoconductive mode) with no illumination, a small amount of current called “dark current” flows through the photodiode. This needs to be compensated for using a second, identical photodiode (Figure 4). WebJan 11, 2024 · The dark current can conceal the photocurrent due to extremely low light levels, so devices having low dark currents should be selected.
