ECSE-2050 Fall 2006 Introduction to Electronics Homework 3 Due Thursday, Sept. 21st Problems 1-4: (Diode Modeling) Reading : Section 3.3, except 3.3.8 (pp.153-159, 163-166) 1. Problem 3.9 2. Problem 3.26 (Use i D =I s e (v/nV T ) ) 3. Problem 3.48. Also find I and V for the circuit in Figure 3.9a if the diode has a piece-wise linear model with V D 0 = .6 V and r D = 50 Ω ( Answer : I = .377 mA, V = -6 mV). 4. Find the Thevenin equivalent of the circuit shown below. Assume g=0.5mA/V Answer: V oc =6V, R th =4KΩ Problems 5-6 (Rectifier Circuits) Reading: Section 3.5 15. Problem 3.76 (Hint: sketch the waveform to help set up the calculations for the fraction of the cycle that the diode conducts and the average output voltage – you can’t just plug values into the formulas) 2 36. Problem 3.86. (Use a half wave rectifier) Answer (a)11.8V (b) 889uF (c) 48V(50%
