Q. With increasing biasing voltage of photodiode, the photocurrent magnitude:
JEE Main
JEE Main 2020
Semiconductor Electronics: Materials Devices and Simple Circuits
A
increases initially and saturates finally
18%
B
increases initially and after attaining certain value, it decreases
29%
C
increases linearly
24%
D
remains constant
29%
Solution:
I-V characteristic of a photodiode is as follows:
On increasing the potential difference the current first increases and then attains a saturation
