Problem # 3
Given the common-collector amplifier (C.C.) in figure 3, determine:
a. The emitter current IE,
b. The collector current IC,
c. The collector-emitter voltage VCE, knowing that βdc = βac = 80.
d. Sketch the AC equivalent circuit, using the re model for the common-collector BJT, and
determine: The input impedance Zi, the output impedance Zo, assuming ro = ∞ and he open-
output voltage gain AV.
Hint: use Thevenin equivalent circuit approach.
