Re-examination of pole splitting of a generic single stage amplifier

Pole splitting on the frequency response of a generic single stage amplifier due to the insertion of a compensation capacitor is re-examined. The Miller's Theorem is discussed in detail and it is shown that the initial dominant pole of an uncompensated amplifier remains dominant after compensation. Input and output impedances are computed to reveal the root loci and bandwidth of these quantities. Simulation results are presented in confirming the analysis.
