UNIVERSITY OF CALIFORNIA College of Engineering Department of Electrical Engineering and Computer Sciences Problem Set #12 Due Tuesday, May 9, 2006 at 5:00 pm EE 105 Spring 2006 1. Using Ebers-Moll Model, determine the terminal currents I B , I B E , I C for the bipolar transistor under the following bias condition: I S = 1E-16A β F = 100 β R = 0.1 (a) V BE = 0.7V, V CE = 5V (b) V BE = 0.7V, V CE = 0.2V 2. Consider the following common-collector amplifier. I S = 1E-16A V A = 20V r oc Æ β F = 100 R L = 1k R S = 1k

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
