Technique to eliminate slow-settling components that appear due to dipoles [multipath compensated amplifiers]

Abstract

Due to their low-voltage compatibility and potential for high-speed operation, multipath compensated amplifiers offer potential for implementation in low-voltage processes. They are not practical for high-speed applications yet because they have low frequency dipoles which result in slow-settling components appearing in the transient response. This work outlines a self-calibration methodology that attempts to extend the performance of multipath compensated amplifiers into the high-speed realm by ensuring pole-zero cancellation to a certain degree of accuracy.
