Dark current in a photo-diode depends on the
Options:
Answer:
B
Solution:
In a photo-diode, the dark current is the current that flows when no light is incident on it. It is essentially the reverse saturation current of the p-n junction diode.
The reverse saturation current is caused by the drift of thermally generated minority charge carriers across the depletion region.
Therefore, the dark current depends on the concentration of minority carriers.
Answer: concentration of minority carriers.
