Unformatted text preview: Report 4: Single Stage BJT Amplifiers: Common Emitter Name: Lab Section: 1 Lab Questions 3.1.2 DC values and gain when the circuit is biased for maximum small signal gain: V IN = V OUT = A v = 3.1.3 Using load line analysis for the pull up resistor (i.e. finding the intersection point of the load line and BJT I-V curve), explain why the BJT will yield very low gain if it is not biased into forward active mode. 3.2.1 What is the input resistance? R in = 3.2.2 What is the measured gain? Is this measured value roughly the same as the gain you measured using ICS? A v = 3.2.3 Why does clipping happen at the top of the output waveform? Why does it happen at the bottom? What is the output voltage swing? 1 1 LAB QUESTIONS 2 Output Voltage Swing = 3.2.4 Why is the capacitor needed when we attach the load? 3.2.5 What is the output resistance of the amplifier? R out = Why does the method work in measuring output resistance? ( Hint: Model the output resistance as being in series with the potentiometer and then apply the voltage divider formula. ) 3.3.3 Compare the respective volumes of the 1 kHz tones produced by the speaker for the following two cases:3....
