Brinson, Mike and Faulkner, D. J. (1995) New approaches to measurement of operational amplifier common-mode rejection ratio in the frequency domain. IEE Proceedings - Circuits, Devices and Systems, 142 (5). pp. 247-253. ISSN 1350-2409

Abstract

Four test circuits for measuring operational amplifier common-mode rejection ratio (CMRR) are described and analysed. Sample results are presented for the uA741, characterising the variation of CMRR with frequency. Two new test circuits and a variation on an existing technique offer significant improvements over previous methods and are capable of accurate measurements on high-performance operational amplifiers.
