Homework #5
Due on 2/8/2026 (Sunday)
From Microelctronic Circuits (Sedra and Smith) 8th edition:
1) 4.4 b, e, g, h, i
2) 4.8
3) 4.37 (Change R = 200 Ω to 500 Ω).
4) 4.43 (do Fig. P4.7b only)
5) 4.51
6) 4.65 (Change the peak amplitude to 10 V and R to 1 kΩ)
7) Sketch the transfer characteristic vo versus vi for the limiter circuits shown below. All diodes begin
conducting at a forward voltage drop of 0.5 V and have voltage drops of 0.7 V when conducting a
current iD ≥ 1 mA.
(a)
(b)
(c)
(d)
8) Sketch and clearly label the transfer characteristic of the circuit below for VI between ± 15 V. Assume
the diodes can be represented by the constant-voltage-drop model with VD = 0.7 V. Also assume that the
Zener voltage is 6.8 V and that rz is negligibly small.
