John Choma was Professor and Chair of Electrical Engineering-Electrophysics at the University of Southern California.
Choma held B.S., M.S., and Ph.D. degrees in electrical engineering from the University of Pittsburgh.〔(''USC Faculty web page for Dr. John Choma'' )〕 His graduate theses were:
* "Design of a Transistor Phasemeter," M.S. Thesis, Universityof Pittsburgh, 1965.
* "Stability Analysis of Class C Transistor Amplifiers,” Ph. D. Dissertation, Universityof Pittsburgh, 1969.
Choma joined the USC faculty in 1980. He taught undergraduate and graduate courses in electrical circuit theory, filters, and analog integrated electronics, and advised industry in subjects relating to broadband analog and high-speed digital integrated circuit analysis, design, and modeling.
He died on August 10, 2014.〔http://www.jcatsc.com/〕
Choma was the author or co-author of some several hundred journal and conference papers and the presenter of dozens of invited short courses, seminars, and tutorials. He authored or co-authored several books in the field of analog circuits and network theory, including:
* The Wiley Interscience text on electrical network theory, "Electrical Networks: Theory and Analysis"〔(''Electrical Networks: Theory and Analysis (Wiley-Interscience, New York, 1985)'' )〕
* Co-author with Professor Wai-Kai Chen〔(''Professor Wai-Kai Chen, University of Illinois, Chicago'' )〕 of the text "Feedback Networks: Theory and Circuit Applications"〔(Feedback Networks: Theory and Circuit Applications (Wiley, New York) )〕
* Co-author with Dr. Greg Rollins of the chapter 8, "Radiation Effects on Semiconductors", of "Space Communications and Nuclear Scintillation"〔(Space Communication and Nuclear Scintillation, edited by N. C. Mohanty (New York: Van Nostrad and Reinhold, chapter. 8, 1991) )〕
* An area editor of the IEEE/CRC Press Handbook of Circuits and Filters.〔(''IEEE/CRC Press Handbook of Circuits and Filters series'' )〕
