Ex. 1 Draw the circuit (1) and calculate (2) the collector-emitter voltage VCE for the Voltage Divider Bias VDB circuit with the following parameters: VCC = 125V, R1= 1.5kn, R2 = 330kn, RC= 1.2km, RE= 4700 and = 100 [3 points) Ex. 2 The VDB circuit of the previous exercise is now capacitor coupled to an AC supply VG(pp) 2mV and a load of RL 6.8km2, a bypass capacitor connects to RE. There is also a generator impedance RG-6500. Draw the new circuit (1) its rt equivalent circuit (1) and find the value of re' (1). Then find the voltage gain AV (2) [5 points) Ex. 3 Draw a two-stage voltage amplifier circuit (2) made up of two capacitor coupled VDB circuits of Ex2, with vin 2mV Vcc=15V, RG = 6500, ß= 100 and RL= 6.8k. Now draw underneath its rt equivalent (3) circuit. For this circuit calculate and the ac collector voltage of the first stage vc7 (2), the total gain AV (3) and the ac output voltage across the load resistor vout (2). You may use results from the previous questions, where needed.
