Abstract

This article describes a method to enhance bandwidth and phase margin of conventional folded-cascode op amps. It achieves a larger bandwidth and/or phase margin in folded-cascode CMOS op amps than those of a conventional one in a given CMOS process. For the same bandwidth the new method allows a larger phase margin, and for a given phase margin a larger bandwidth can be obtained. Also, for equal bandwidth, power consumption of the new folded-cascode is lower than the traditional one with similar load.
