Unformatted text preview: Experiment 5: Single Stage BJT Amplifiers: Common Collector and Common Base 1 Objective In lab 4, we explored the properties of a common emitter amplifier. However, even though the amplifier has an extremely high gain, its high output impedance prevents it from properly driving the speaker. In this lab, we will investigate the properties of two other single-stage amplifier configurations: the common collector (CC) and the common base (CB). You will be applying the techniques learned from lab 4 to evaluate the input impedance, output impedance, and gain for both of these amplifier configurations. If you need a review of these techniques, please refer to lab 4 now. By the end of this lab, you should be able to model any single stage amplifier using its two-port model as well as identify the strengths and weaknesses of each single-stage amplifier configuration. 2 Materials The items listed in table 1 will be needed. Note: Be sure to answer the questions on the report as you proceed through this lab. The report questions are labeled according to the sections in the experiment. Also, note that there is an accompanying post-lab appended to the end of the lab report. CAUTION: FOR THIS EXPERIMENT, THE TRANSISTORS CAN BECOME EXTREMELY HOT!!!...
