What is Miller’s theorem?

 

When an impedance Z is connected between the input (1) and output (2) terminals of a network which provides a voltage gain Av as shown in the Fig.(a), an equivalent circuit which gives the same effect can be drawn by removing Z and connecting an impedance  across input terminals and another impedance    across output terminals as shown in Fig. (b). This theorem is called Miller’s theorem.
