The following Common Emitter (C.E.) amplifier is biased with a current source I. It has β = 100, VA = ∞, VT = 25mV, and rπ = 25kΩ. Draw the small signal equivalent circuit including the Hybrid-π with the βIb currentsource model. Label the input (Rin), output (Rout), and base (Rib) resistances. Find Rib, Rin, Rout, and the voltage gain (vo/vsig).
