Consider the common-emitter amplifier of Fig. under the following conditions: Rsig = 5 kΩ, RB1 = 33 kΩ, RB2 = 22 kΩ, RE = 3.9 kΩ , RC = 4.7 kΩ, RL = 5.6 kΩ , VCC = 5 V. The dc emitter current can be shown to be IE _0.3 mA, at hich β = 120. Find the input resistance Rin and the midband gain AM. If CC1 = CC2 = 1 μF and CE =20 μF, find the three hort-circuit time constants and an estimate for fL.
