A. What is the depletion region; what causes it; and why does it have a strong electric field? B. Use an energy band diagram to explain fully why a forward bias across a pn junction results in a large net current. C. Draw the I vs V curves for (a) a silicon rectifier diode, (b) a super barrier diode, (c) a red LED, and (d) a blue LED. What is the approximate voltage on each type of diode when the current is 20mA? D. Design a circuit which will protect the sensitive inputs of a CMOS gate and explain how it does so.
