A hierarchy of input stages for current feedback operational amplifiers

A. A. Tammam, K. Hayatleh, B.L. Hart, F.J. Lidgey

Abstract

This paper considers the trade-offs involved in the design of six new input stages intended to improve the performance of a current feedback operational amplifier (CFOA), over that possible using an established input circuit configuration, with respect to three major characteristics, viz, common mode rejection ratio (CMRR), offset voltage and skew rate.
