Q. 14.10 In a p-n junction diode, the current I can be expressed as
where is called the reverse saturation current,
is the voltage across the diode and is positive for forward bias and negative for reverse bias, and
is the current through the diode,
is the Boltzmann constant
and
is the absolute temperature. If for a given diode
and
then
(c) What is the dynamic resistance?
Dynamic Resistance =
Resistance change = 0.7 - 0.6 = 0.1
Current change = 2.967(calculated in prev question)
Therefore
,
