Analysis of multistage amplifier-frequency compensation

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