Question

Photodiode characteristics forward or reverse bias

Answer 1

Answer:

A photodiode continually operates in a reverse bias mode. The characteristics of the photodiode are shown clearly in the following figure, that the photocurrent is nearly independent of reverse bias voltage which is applied. For zero luminance, the photocurrent is almost zero excluding for small dark curren

Answer 2

Answer:

mark me as brainliest and support me to give more valuble answers

Explanation:

As fractional change in minority charge carriers is more than the fractional change in majority charge carriers, the variation in reverse saturation current is more prominent.
