Unformatted text preview: Report 5: Single Stage BJT Amplifiers: Common Collector and Common Base Name: Lab Section: 1 Lab Questions 3.1.2–4 CB amplifier parameters: A v = R in = R out = 3.1.5 Suppose the source resistance of V IN is 50 Ω. Will the CB amplifier perform well in amplifying the signal from v in ? Why? 3.2.2 DC voltage values when biased at maximum output voltage swing: V IN = V OUT = 3.2.3 CC amplifier parameters: A v = R in = R out = Output Voltage Swing = 1 2 POST-LAB QUESTIONS 2 3.2.4 Another name for the CC amplifier is the emitter follower. Based on the gain that you have found, why do you think it is given this name? 3.3.3 Is the tone louder, softer, or about the same as when the signal was directly applied to the speaker? Explain your observations. Hint: Consider the gain and I/O impedances. 2 Post-lab Questions 2.1 Common Collector Amplifier as a Voltage Buffer 1. Even though the common collector amplifier has roughly unity gain, why is it still a useful amplifier configuration?...
