Abstract :
Frequency-compensation techniques of single-, two- and three-stage amplifiers based on Miller pole splitting and pole-zero cancellation are re-analyzed. The assumptions made, transfer functions, stability criteria, bandwidths, and important design issues of most of the reported topologies are included. Several proposed methods to improve the published topologies are given. In addition, simulations and experimental results are provided to verify the analysis and to prove the effectiveness of the proposed methods
