Note the ac source has a magnitude of 20 mV. NOTE: Only the 'full' schematics are requested below, not the ac small signal models. You may use the equations derived in lecture (or from the text); there is no requirement to rederive them. 1. For the circuit shown in Fig. 1, compute Avi, Avs, Ai (current gain), A- (power gain), Rin and Rout. 2. Redraw the circuit as a common base, and compute the same 4 gains as well as R., and Rout 3. Redraw the circuit as a common collector amplifier (note this requires that Rc = 0), and compute Avi, Avs, A, (current gain), Ap (power gain), Rin and Rout RC 5k C2 # Vout RL 2k 15 Vec R1 4.7k C1 71μ R2 2.5k Vin W Q1 2210 Rs 50 Vs RE CE SINE() AC 0.02 2.2k 15μ .model 2210 NPN (Bf=100) Figure 1 A simple common emitter amplifier circuit.
