1 2 Zener Diode R 200 ohm VCC = 30 Volts R Load + _ V L o a d ECE 255 ELECTRONIC ANALYSIS AND DESIGN Fall 2011 Homework 2 Due Wednesday, September 14 5:00 p.m. Room MSEE 180 – Drop Box COURSE WEBSITE: http://cobweb.ecn.purdue.edu/~ee255/ 1) Text problem 3.74, page 139 2) Continue Text problem 3.74, page 139 – (c) Repeat using a diode model containing an ideal diode, a voltage source, V 0 = .65 V, and resistor, R 0 = 200 . 3) Using a Zener diode with |V BR | = 15 V and R Z = 25 in the simple voltage regulator shown below, having V CC = 30 V, calculate the load voltage, V Load , when (a) I Load = 0 (b) I Load = 1 mA (c) I Load = 10 mA (d) I Load = 70 mA (e) What is the maximum possible current that can be drawn by the load before the Zener diode stops providing any regulation? (f) If the 30 V supply, V CC , has a ripple, CC 0.1V v = , what is the ripple seen at the load when 50 mA is being drawn? 4)
