Purpose: In this experiment, were examined the current amplification (A I ), voltage amplification (A V ), input impedance, Z IN , and output impedance, Z OUT , characteristics of a Common-Collector Amplifier. Theory: The Common-Collector, or emitter-follower, is an extremely useful type of amplifier. The collector is common to both input and output. This is most easily seen in the small-signal equivalent model. Pay close attention to the input and output impedance calculations and measurements. Procedure: 1. Use a 5 k Ω variable resistor as R L . Adjust the value so that it is exactly 500 Ω . 2. Construct the amplifier circuit. Determine the Q-point conditions, i.e., measure I C,Q and V CE,Q .

    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.
