WebJan 11, 2024 · The photodiode. The photodiode is a two-element P-N or PIN junction that is exposed to light through a transparent body or cover. When light strikes the junction, a … WebDark current noise is the constant current that exists when no light is incident on the photodiode. This is the reason it is called dark current. As shown in Eq. (4.2.8), this dark current is the same thing as the reverse saturation current I s because the photodiode is always reversely biased. Because of the statistical nature of the carrier ...
