Unformatted text preview: Q 1 in active region. b) For R C = 500 W , calculate the maximum value of V BE that permits the operation of Q 1 in active region . c) Consider now V BE = 0.7V and R C = 1k W . A small-signal v be is applied in series with V BE as shown in Fig. 3. Draw the small-signal equivalent circuit and find the small-signal voltage gain v o / v be . For v be = 0.004sin 1 t-0.001sin 2 t (V), calculate the expressions for the total instantaneous quantities v O (t), i C (t) and i B (t).
