Question

10. (17 points) The purpose of this problem

is to practice small-signal analysis of a diode

resistor circuit including the DC bias

analysis. From the last homework

assignment, you hopefully remember doing

Vout VS. Vin analysis on a circuit such as the

one shown here. Assume R₁=1 ks,

R₁

R₂

Vout

R₂-3 k2, an exponential diode model (unless specified otherwise) with Is = X3ID nA, and

that the average value of Vin is zero in this circuit. [DO NOT POST OR SHARE ANY

(a) Determine the voltage of Vz, a DC ideal voltage source, required to make the forward

diode bias current ID = 1000 Is. Use this value of Vz for parts (b) and (c) of this problem.

(b) Draw the small-signal model of the circuit and label all resistor values on your

drawing. (c) Determine a single value of the transfer function, H(f) at 1 kHz for this

circuit. (d) Repeat part (c) assuming Ip = 0 A and thus Vz=0 V. (e) Repeat part (c)

using Vz-1 V and an "ideal" (perhaps better called a "piece-wise linear") diode model

with Von 0.7 V and Ron=1 kn.
