Solved Problem Problem 1 1- Consider the circuit shown in Fig. 1. 15 = 6.95x1-0-16A and p- 100 for the npn BJT (Qr), Vr=25mV and Vcc 5V. (Consider the npn BJT in active region if Vec < VBcon = 0.4v) For VaE 0.7V, determine the maximum value of R6 that permits the operation of Qr region. For Rc 500C1, calculate value of Vee of Qr consider now V36 0,7V and Rc Lko. A small-signal yr" is applied in series with Vsr as shown 2. Draw the smalf-signal equivalent circuit find the small-signal voltage gain vo/va. . For v6" 0.004sinort-0.001-sinol2t (V), the expressions for the total instantaneous quantities vs(t), ig(t) is(t). rie.f a) b) c) Vbe Vee Fig.2
