The following figure shows a schematic symbol and constructional detail of a photo diode.Working of a Photo DiodeIt is a reverse-biased diode. Reverse current increases as the intensity of incident light increases. This means that reverse current is directly proportional to the intensity of falling...
Some photodiodes will look likea light-emitting diode. They have two terminals coming from the end. The smaller end of the diode is the cathode terminal, while the longer end of the diode is the anode terminal. See the following schematic diagram for the anode and cathode sides. Under the ...
An equivalent circuit helps us to understand and predict the real-life functionality of an electronic component. For photodiodes, an equivalent circuit model is an essential analytical tool, because simply inserting a photodiode symbol into a schematic doesn’t tell you much about the signal that w...
