Question

A common emitter amplifier as shown in Figure Q2 has the following parameters, β = 100, R1
= 33K, R2 = 10K, RC = 3K3, RE = 1K, ro =  and VBE = 0.7 V.
State all assumptions made.
i. Check whether βRE>>10R2 is satisfied
ii. Use the appropriate approach of analysis to determine the Quiescent point; IBQ,
ICQ and VCEQ.
iii. Draw the small signal equivalent circuit. Determine input impedance, Zin, output
impedance, Zout, and the voltage gain, AV, if RL=20kΩ.
