PN junction: Calculate the change in diode voltage that will cause a factor of 10 increase in current.
Consider an ideal pn junction diode at T=300K operating in the forwared bias region. Calculate the change in diode voltage that will cause a factor of 10 increase in current.
The ideal diode equation is:
where Is=saturation current; Va=applied voltage; T=temperature; n=diode ideality factor =1.
In forward bias, the Exponential Term dominates, so we can neglect the factor in ...
With good explanations and calculations, the problem is solved.
