Carnegie Mellon University Department of Electrical and Computer Engineering 18-100 Fall 2009 Introduction to Electrical and Computer Engineering Homework 6 - Due Tuesday, October 20, 2009 Please do all numbered problems listed below from the Rizzoni text. For our purposes, assume the base-emitter region has a turn-on voltage of 0.6V, and the collector-emitter saturation voltage is 0.2V. 1. Problem 10.11. Don’t use the 2N3904 characteristics, just let β = 100 for this problem. 2. Problem 10.12. Let the input voltage be 8.1V, base resistor be 75k Ω , collector resistor be 2 k Ω , and β = 100. 3. Problem 10.14. Use Vce,sat = 0.2V and β = 100. Let the base resistor be 100k Ω and the collector resistor be 5 k Ω . 4. Problem 10.16. Very similar to problem 10.11 (#1 above). Again, don’t use the 2N3904 characteristics, just let β = 100 for this problem. Now you have both a collector and emitter resistor. 5. Problem 10.6. Change the voltage source to 12V, let β = 100, collector resistor be 2k Ω , and emitter resistor be 1k Ω .

    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.
