Introduction The lab 7 report, Common Collector Amplifier, is presented herein. The lab took place on July 28 2020. The pre-lab is at the end of the report in the appendix. Objective The objective of this lab is to examine the CC amplifier and to learn a property that it has called buffering. The lab also lets us study multistage amplifiers Circuit Under Test The following figure contains the circuit being used for the experiment. 1

C3 The CC amplifier has a very high input impedance and a very low output impedance. This trait of it allows it to be used as a unity gain buffer. This means that even if there is a heavy load resistance the equivalent resistance would still be pretty small, meaning that there would be a good overall voltage gain. Appendix P1&2 3
