Question

15 Vcc RC 5k C2 R1 4.7k Vout 4H C1 Q1 2210 RL in 2k 50 71? RE 2.2k CE R2 2.5k SINEO AC 0.02 15? ·model 2210 NPN (Bf=100) Figure 1 A simple common emitter amplifier circuit. 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 themm 1. For the circuit shown in Fig. 1, compute Avi, Avs, Ai (current gain), Ap (power gain), Rin and Rout 2. Redraw the circuit as a common base, and compute the same 4 gains as well as Rin and Rout 3. Redraw the circuit as a common collector amplifier (note this requires that Rc -0), and compute Avi, Avs, Ai (current gain), Ap (power gain), Rin and Rout
