E. J. (ED) KENNEDY received his Ph.D. in electrical engineering in 1967 from the
University of Tennessee at Knoxville. Before joining the faculty of the University
of Tennessee, he held positions at the Arnold Engineering Development Center and
the Oak Ridge National Laboratory. Ed’s research interests include nuclear instru-
mentation, strapdown gyroscope rebalance electronics, hybrid thick-film electronics,
switching regulators, and analog integrated circuits. He was appointed Fulton
Professor of Electrical Engineering in 1983, has been a Ford Foundation Teaching
Fellow, and has received the NASA Commendation Award. Ed’s books include
Operutional Amplifier Circuits ( 1988) and the forthcoming Semiconductor Devices
and Circuits. He is married, has three daughters, and enjoys tennis, gardening, and
growing roses.

ROBERT J. MATTHYS retired from Honeywell’s Systems & Research Center in
Minneapolis, Minnesota as a research engineer, and is still associated with the Center
on a part-time basis. He has over 38 years of experience in optical, mechanical, and
electronic design. He has written a book on crystal oscillator circuits, holds five
patents (with two pending), and has published 17 technical papers. Among his other
achievements of which he is proud are seven children and four grandchildren. His
interest in crystal oscillators began when he was asked to design one, and found the
reference articles disagreed with each other and some were even obviously wrong.
PHIL PERKINS is a Fellow of LTX Corp. in Westwood, Massachusetts. His work
includes analog instrumentation and system design for the LTX semiconductor test
systems. Most recently, he has developed test heads for the Synchromaster line of
mixed-signal semiconductor test systems. Prior to co-founding LTX, Phil worked
eight years at Teradyne, Inc. in Boston. He received his degrees in electrical engi-
neering from the Massachusetts Institute of Technotogy. Phil’s interests include
local and national activities in the United Methodist Church, home computer
hobbying plus consulting for friends, vegetable gardening, and bicycling. He lives
in Needham, Massachusetts, with his lovely wife Laurie.

BOB PEASE graduated from the Massachusetts Institute of Technology in 1961 with
a B.S.E.E. He was employed at George A. Philbrick Researches from 1961 to 1975,
where he designed many operational amplifiers, analog computing modules, and
voltage-to-frequency converters. Bob joined National Semiconductor in 1976.
Since then, he has designed several ICs, including regulators, references, voltage-
to-frequency converters, temperature sensors, and amplifiers. He has written about
60 magazine articles and holds eight patents. Bob has been the self-declared Czar of
Bandgaps since 1986, and enjoys hiking, backpacking, and following abandoned
railroad roadbeds. He also designs voltage-to-frequency converters in his spare
time. Bob wrote an award-winning series of articles on troubleshooting analog
circuits which appeared in EDN Magazine in 1989, and which will be expanded
into a book to be published by Butterworth-Heinemann. Bob currently writes a
column about analog circuits which appears in Electronic Design Magazine.

JIM K. ROBERGE has been at the Massachusetts Institute of Technology since
1956, initially as a freshman and currently as professor of electrical engineering. In
between, he received the S.B., S.M., and Sc.D. degrees in electrical engineering and
held various research and academic staff appointments. His teaching and research
interests are in the areas of electronic circuits and system design. Much of his
research is conducted at M.I.T. Lincoln Laboratory and is involved with communi-
cations satellites. He is the author of Operational Amplifiers: Theory and Practice
