In given figure a silicon diode is carrying a constant current of 1 mA. When the temperature of the diode is 20°C, VD is found to be 700 mV. If the temperature rises to 40°C, VD becomes approximately equal to
Answer : Option A
Explanation :
Id = Io(eVD/ηVT - 1)
By considering , then
= eVD/ηVT
Id is constant according to question,
VD a T
