Abstract

A new method for the calculation of Miller effect on the frequency response and on the input and output impedances of feedback amplifiers is presented. It is based on the Feedback Decomposition Theorem, a recently presented evolution of Miller´s Theorem. Application results obtained with this method are compared to those of Miller´s Theorem application, through analysis and SPICE simulations, proving its accuracy.
