1 EECS 215 Winter 2007 Problem Set #5 Assigned: Wednesday, 10/10/07 Due: Wednesday, 10/24/07 (But do not wait until after Exam 1 to start!) Homework is due at the beginning of lecture. Reading Assignment: Review A&S through Chapter 4, class notes 1. A&S 5.92, determine the voltage gain v o /v i for the amplifier below. 2. Determine the diode current and voltage for the circuit to the right for V DD =4V, R=2k , I 0 =10 -15 A, and kT/q=0.026V. Use the diode model where ( ) 1 / 0 = kT qV D D e I I . To solve this problem, let’s use multiple techniques. a. Graphical technique: For this technique, you can find the solution by plotting the I-V relations of the resistor and the diode on the same axes. First, plot I D vs. V D for the diode. On the same axes, plot (not draw) the “load line” for the resistor, given by ( ) R V V I D DD D / = . The intersection point of the two curves provides the solution for I D and V D . b. Numerical technique: The I-V relations for the diode and resistor provide a system of 2 equations with two unknowns (I D and V D ). Note that this is a “transcendental equation”. You can solve these numerically using a variety of techniques, including built-in Matlab solvers, advanced solvers on calculators, or an iterative method. You must indicate equations and methods used to solve the equation.
