fotodiodami
Fotodiodi, also known as photodiodes, are semiconductor devices that convert light into an electrical current. They are a type of photodetector and are widely used in various electronic applications. The fundamental principle behind a photodiode's operation is the photoelectric effect. When photons with sufficient energy strike the semiconductor material, they can excite electrons, creating electron-hole pairs. An internal electric field within the photodiode then separates these charge carriers, causing a current to flow.
There are several types of photodiodes, each suited for different applications and spectral ranges. Common types
Fotodiodi are typically employed in circuits where they are reverse-biased, meaning a voltage is applied that
