John Choma earned his B.S., M.S., and Ph.D. degrees in electrical engineering from the University of Pittsburgh in 1963, 1965, and 1969, respectively. He is Professor and Chair of Electrical Engineering-Electrophysics at the University of Southern California, where he teaches undergraduate and graduate courses in electrical circuit theory, filters, and analog integrated electronics. Prof. Choma consults in the areas of broadband analog and high-speed digital integrated circuit analysis, design, and modeling.

Prior to joining the USC faculty in 1980, Prof. Choma was a senior staff design engineer in the TRW Microelectronics Center in Redondo Beach, California. His earlier positions include technical staff at Hewlett-Packard Company in Santa Clara, California, Senior Lecturer in the Graduate Division of the Department of Electrical Engineering of the California Institute of Technology, lectureships at the University of Santa Clara and the University of California at Los Angeles, and a faculty appointment at the University of Pennsylvania.

Prof. Choma, the author or co-author of some 150 journal and conference papers and the presenter of more than sixty invited short courses, seminars, and tutorials, is the 1994 recipient of the Prize Paper Award from the IEEE Microwave Theory and Techniques Society. He is the author of a Wiley Interscience text on electrical network theory and a forthcoming text on integrated circuit design for communication system applications. Prof. Choma has contributed several chapters to five edited electronic circuit texts, and he was an area editor of the IEEE/CRC Press Handbook of Circuits and Filters.

Prof. Choma has served the IEEE Circuits and Systems Society as a member of its Board of Governors, its Vice President for Administration, and its President. He has been an Associate Editor and Editor–In–Chief of the IEEE Transactions on Circuits and Systems, Part II. He is an Associate Editor of the Journal of Analog Integrated Circuits and Signal Processing and a former Regional Editor of the Journal of Circuits, Systems, and Computers.

A Fellow of the IEEE, Prof. Choma has been awarded the IEEE Millennium medal and has received three awards from the IEEE Circuits and Systems Society namely, the Golden Jubilee Award, the 1999 Education Award, and the 2000 Meritorious Service Award. He is also the recipient of several local and national teaching awards. Prof. Choma is a “Distinguished Lecturer” in the IEEE Circuits and Systems Society.

Radio Frequency Filter Design addresses the analysis, design, and implementation of high performance analog filters suitable for data processing, information transmission, and radio frequency (RF) communication systems realized in modern monolithic circuit technologies. Several reasons underlie the necessity of suitable filters in these systems. Foremost among these reasons is that they can be used to match or otherwise modify circuit impedances to ensure the reasonably efficient transfer of signal power between driver and load ports. Maximum power transfer is a critical design objective in high frequency communication networks because the anemic levels of signal power indigenous to such systems increase the risk of contaminating signal information with omnipresent electrical noise. Filters can also be employed to improve the high frequency responses of active circuits by mitigating the deleterious impact of active device capacitances. They can even improve the observable linearity of certain types of active systems by achieving a sharp attenuation of the high frequency harmonics incurred by inherent active device nonlinearities. The RC and RLC filters implicit to electronic power supplies comprise simple examples of filters designed to obviate undesirable harmonics of power line frequencies. Finally, filters can annihilate unwanted signals by offering designable frequency selectivity. For example, low-pass filters all but eliminate undesired signal or noise energy at very high frequencies, bandpass filters offer frequency selective signal processing, as well as a reduction of cumulative output noise energy, and stopband filters obviate the energy of specific frequencies lying within the frequency spectra of signal information earmarked for processing.
