a) A silicon diode has a doping profile such that ND = ax3. What is the depth of the junction assuming the p side is uniformly doped with NA per cubic cm. Assume the x origin is at an ideal ohmic contact on the n side of the diode.b) Sketch the energy band diagram for a Si p/n+ diode doped with NA acceptor and ND donor atoms. Assume both sides are non-degenerate.c) For the diode in problem 1b, if NA = 1015 and ND =1016 what is the built in potential (numeric value) of the diode?d) What is the origin of avalanche breakdown in a diode?
Design limiter circuits using only diodes and 10-k ohm resistors to provide an output signal limited to the range: (a) -0.7V and above (b) -2.1V and above (c) ±1.4V Assume that each diode has a 0.7-V drop when conducting.
Compute the value of ES(N) or OS(N) for a given number N. First, you use switch 0 to represent ES or OS. We use switch[0] = 0 to indicate the computation of ES(N) and switch[0] = 1 to indicate the computation of OS(N).
