Question

Part I (30 points): Reference to Multi-stage Amplifier. FET Data (Cd 2pF, Cgs4pF, 1. For the multi-stage amplifier of the figure, calculate the polarization voltages and current collector of each stage. Also, calculate the voltage gain for each stage and the overall voltage gain (transfer function) for the multi-stage amplifier. Calculate Vout. Repeat the previous steps using a load resistance of 2.2k2, Calculate Vout. Calculate the input and output impedances and the cutoff frequencies (fi & fa) for the cascade amplifier. Draw the equivalent circuit for each stage·4(昀泪 2. 3. Awa FLこ 2 +20 V 2.2 kQ 0.5 μF 0.5μF β 200 /mv 0.05 μF 4.2 k2 3.0 ΜΩ 100μF 100μF 680 Ω
