The capacitance of a p-n junction diode:
  • a)
    Does not change with the increase in the forward bias voltage
  • b)
    Decrease with the increase in the forward bias voltage
  • c)
    Increase exponentially with the increases in the forward bias voltage
  • d)
    Increase linearly with the increase in the forward bias voltage
Correct answer is option 'C'. Can you explain this answer?

The capacitance of a p-n junction diode:a)Does not change with the inc...
During forward Bias, the diffusion capacitance is the dominant capacitance.
τ = mean lifetime of minority carriers
If = forward current
As forward current Increase exponentially,
The junction capacitance increases exponentially on forward bias.
