Assume that R C is made large compared with r o in the CB amplifier of Fig.

Question:

Assume that R_Cis made large compared with r_oin the CB amplifier of Fig. 3.15. Use the equivalent circuit of Fig. 3.17 and add r_obetween the input (emitter terminal) and the output (collector terminal) to calculate the output resistance when

(a) The amplifier is driven by an ideal current source.

(b) The amplifier is driven by an ideal voltage source. Neglect r_b.
