Ian Galton
Department of Electrical Engineering


Fractional-N phase-locked loops (PLLs) are widely used as RF local oscillators in wireless communication systems. Their performance is critical in such applications, so they are a subject of intensive research. This tutorial talk will provide explanations of both analog and digital fractional-N PLLs as well as techniques that mitigate several practical implementation issues. Many of the concepts are presented in the context of fractional-N PLL integrated circuit case studies supported by measurement results.

Speaker Bio

Ian Galton received the Sc.B. degree from Brown University in 1984, and the M.S. and Ph.D. degrees from the California Institute of Technology in 1989 and 1992, respectively, all in electrical engineering. Since 1996 he has been a professor of electrical engineering at the University of California, San Diego where he teaches and conducts research in the field of mixed-signal integrated circuits and systems for communications. Prior to 1996 he was with UC Irvine, and prior to 1989 he was with Acuson and Mead Data Central. His research involves the invention, analysis, and integrated circuit implementation of critical communication system blocks such as data converters and phase-locked loops. In addition to his academic research, he regularly consults at several semiconductor companies and teaches industry-oriented short courses on the design of mixed-signal integrated circuits. He is a Fellow of the IEEE, and has served on a corporate Board of Directors, on several corporate Technical Advisory Boards, as the Editor-in-Chief of the IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, as a member of the IEEE Solid-State Circuits Society Administrative Committee, as a member of the IEEE Circuits and Systems Society Board of Governors, as a member of the IEEE International Solid-State Circuits Conference Technical Program Committee, and as a member of the IEEE Solid-State Circuits Society Distinguished Lecturer Program.
