Using a computer simulation, verify the results of Exercise Ex 6.15 for the multi transistor amplifier.
Data From Exercise Ex 6.15:-


Ex 6.15: For each transistor in the circuit in Figure 6.69, the parameters are: B = 125, VBE (on) = 0.7 V, and r = . (a) Determine the Q-points of each tran- sistor. (b) Find the overall small-signal voltage gain A = Vo/Vs. (c) Determine the input resistance R; and the output resistance Ro. (Ans. (a) Icoi = 0.364 mA, VCEQ1 = 7.92 V, Icq2 = 4.82 mA, VCEQ2 = 2.71 V (b) A = -17.7 (c) Ri 4.76 ks, Ro=43.72) =
