Ten diodes are forwardbiased in parallel and operated at a, Ask an Expert

Engineering

Ten diodes are forwardbiased in parallel and operated at a total current of 100 mA. Allten 20mA, 0.7V diodes are all identical, with n=1.
a) What current flows in each in each diode?
b) What is the small signal resistance of each diode, and the equivalent resistance of all ten diodes in combination?
c) What is theincremental resistance of a single diode conducting 100mA?
d) If each of thediodes has a series resistance of 0.2 W representing junction wire bonds, what is the equivalent resistance of the ten parallel-connected diodes?
e) What connection resistance would a single diode conducting 100 mA need in order tobe equivalent?
