Question 98: Semiconductors and Logic Gates

Question

The photodiode is used to detect the optical signals. These diodes are preferably operated in reverse biased mode because :

Accepted Answer

A photodiode is reverse biased. When light falling on it produces charge carriers, the fractional change, in minority carriers is high since the original current is very small.

Answer

fractional change in majority carriers produce higher forward bias current

Answer

fractional change in majority carriers produce higher reverse bias current

Answer

fractional change in minority carriers produce higher forward bias current

Answer

fractional change in minority carriers produce higher reverse bias current
