Question 1 Recall that Vcc = 22V, R1 = 39k2, R2 = 3.9k2, Rc = 10k2, RE = 1.5k2 and Cg is a bypass capacitor. At the above Q-point, the small signal h-parameters are as follows: hựe = 100, hie = 1.2kN, hoe and hre are assumed to be zero Rc HE i) Draw the small signal equivalent circuit (include C¡ and C2). E RE CE Fig 1 ii) Neglecting C1 and C2, find (showing your working steps): a) The input impedance, Zi; expression relating Vi and Ii should be included in your working. b) The output impedance, Zo; expression relating Vo and Io should be included in your working. c) The no load voltage gain, AvNL; iii) If an input AC source applied to V; has a source resistance of Rs = 700 Q and open circuit AC voltage of Vs = 20 mV (Vpp), find Vo (Vpp). Suggestion: apply the parameters obtained in the previous question. iv) With the above source applied to Vi, now a load resistance of RL = 1 k2 is connected between Vo and ground. Find the resulting loaded output voltage, VL (Vpp). in
