An Emitter follower with a BJT biased at Ic = 1mA and having β = 100 is connected between a source with Rsig = 20kg and a load RL = 1kg.
a) find Rin, vb/vsig, and v0/vsig
b) If the signal amplitude across the base-emitter junction is to be limitd to mV, what is the corresponding amplitude of vsig and v0 ?
c) Find the open Circuit voltage gain Gv0 and the output resistance Rout. Use these values first to verity the value of Gv obtained with RL reduced to 500Ω
