Q1412
The width of depletion layer of a P-N junction
A.
Decreases with light doping
B.
Increases with heavy doping
C.
Is independent of applied voltage
D.
Is increased under reverse bias
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
The total width of the depletion region is a function of applied reverse-bias and impurity concentration. Forward bias decreases the depletion region width whilst reverse bias increases it.
