Analysis of Multistage Amplifier–Frequency Compensation by Ka Nang Leung and Philip K. T. Mok
Abstract—
Frequency-compensation techniques of single-, twoand
three-stage amplifiers 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 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. |
