Abstract

This paper presents a new compensation method for fully differential two-stage CMOS operational transconductance amplifiers (OTAs). It employs a hybrid cascode compensation scheme, merged Ahuja and improved Ahuja style compensations, for fast settling. A design procedure for minimum settling time of the proposed compensation technique for a two-stage class A/AB OTA is described. To demonstrate the usefulness of it, three design examples are considered.
