Suppose the BJT drawn has Ic = 1 mA when VBE = 0.6 V.

(a) Draw the transfer function plot for Rin for the range 10 kΩ < Rin < 100 kΩ, assuming Rin < ZL

for the entire range.

(b) Assuming an ideal BJT, calculate the output impedance at the slave BJT's collector node.

(c) Justify: what is the danger if Z₁ > Rin?
