(a) Show that if the emitter follower of satisfi es the condition gm(Rsig 1 rb) 5 1, then, as long as C 5 0, we have a` 5 a0 and Zo` 5 Zo0. (b) Find the current to which the emitter follower of has to be biased in order to achieve the condition of part (a). (c) Sketch and label the magnitude plot of a(jf) and Zo(jf) for the follower of part (b) if C 5 1 pF. Assume z is negligible at the break frequency of each plot. Verify with PSpice.
