Unformatted text preview: 1 ECE2c Problem set #5: Problem 1: Common-emitter amplifier without emitter degeneration. The bjt has beta=100 and Va=100 V. Vcc is 10 V. RL=2 KOhms and Rgen=2 KOhm. Reac is zero Ohms Bias: Set the collector voltage at 6 V, the emitter voltage at 3 V. The DC collector current is to be 1 mA. Pick Rb2 so that the DC current through it is 20 times the base current. Rc RL Rgen Rb1 Rb2 Redc Reac Vcc a) Give all resistor values b) Find the small signal Vout/Vin, Vin/Vgen and Vout/Vgen c) Find the amplifier input and output impedance d) Find the maximum positive-going and negative going outputs. Problem 2: Common-emitter amplifier with emitter degeneration. The bjt has beta=100 and Va=100 V. Vcc is 10 V. RL=2 KOhms and Rgen=2 KOhm. Reac is 100 Ohms Bias: Set the collector voltage at 6 V, the emitter voltage at 3 V. The DC collector current is to be 1 mA.
