I am interested in knowing a little more about Current-Feedback amplifiers that are so much the rage these days. Does anybody know some good trade magazine articles or journal articles that deal with these devices?

Although current-feedback amplifiers have been getting a lot of "press" lately, they have been around for quite some time. For example, the Analog Devices AD521/524 instrumentation amplifiers and the PMI AMP-01 inst. amp. all use active current feedback and are relatively old. One good place to start is with the book: Analogue IC Design: the current-mode approach Edited by - C. Toumazou, F.J. Lidgey, & D.G. Haigh Published by - Peter Peregrinus Ltd, London, 1990 ISBN 0 86341 215 7 This is an edited volume with chapters on many different aspects of current-mode design. (Note: I am one of the authors. I offer this information only for your benefit, not as a sales pitch.) Chapter 16, Applying "Current Feedback" to Voltage Amplifiers, was written by Derek Bowers of Analog Devices/PMI and is a good review of the field. If you are more into journal and trade articles, here are a few references: R. J. Van de Plassche, "A wide-band monolithic instrumentation amplifier", IEEE Journal of Solid State Circuits, vol. SC-10 Dec. 1975 A. P. Brokaw and M. P. Timco, "An improved monolithic instrumentation amplifier", IEEE Journal of Solid State Circuits, vol. SC-10, Dec. 1975 C. T. Nelson, "A 0.01% linear instrumentation amplifier", ISSCC Digest of Technical Papers, Feb. 1980 D. F. Bowers, "A versatile precision instrumentation amplifier", ESSIRC '83 Digest of Technical Papers, Sept. 1983 (PMI AMP-01) S. A. Wurcer and L. Counts, "A programmable instrumentation amplifier for 12-bit resolution systems", ISSCC Digest of Technical Papers, Feb. 1982 (Analog Devices AD524) D. F. Bowers, "A precision dual 'current feedback' operational amplifier", BCTM '88 Digest of Technical Papers, Sept. 1988 (PMI OP-260) I've tried to pick references that are representative of commercially viable products or are of general interest. I'm sure there are more, but these should get you started. You will undoubtedly find more references in these papers. Happy reading! Scott T.
