Dr. Jun Fan, associate professor of electrical and computer engineering at Missouri University of Science and Technology, has been named a Fellow of the Institute of Electrical and Electronics Engineers.
Fan, who also is director of the Electromagnetic Compatibility Laboratory and National Science Foundation Industry/University Cooperative Research Center for Electromagnetic Compatibility at Missouri S&T, is being recognized for contributions to power delivery networks in printed circuit designs.
In electronics design, all integrated circuits need power to function, Fan says. A power delivery network is to supply power and provide “ground” for current flow.
“It sounds simple, but it can become very complicated in a modern circuit, such as in a computer or a cellphone, where hundreds or thousands of circuit elements are involved,” Fan says. “When signal speeds increase (faster CPU, faster memory bus, faster USB) at the circuit level, high-frequency current flow becomes more difficult, and noise generated due to circuit operation increases as well. Without a proper design, integrated circuits may not be powered up correctly and thus couldn’t work normally. Further, the generated electromagnetic noise could propagate in the power delivery network, interfering with other devices and radiating to the environment.”
Power delivery network (PDN) modeling and design for high-speed systems has been a core design issue for over 20 years. Without a proper PDN design, digital circuits cannot operate normally at high speed. For 15-plus years, Fan has contributed to the understanding, modeling and design of the PDN in high-speed designs, and he provided a systematic, physics-based approach to guide pre-layout design that is quantitative. His technical contributions have significant impact on the high-speed designs that are widely used in modern high-speed, high-performance computing, communication, and networking systems and devices.
Fan earned bachelor and master of science degrees in electrical engineering from Tsinghua University, Beijing, China, in 1994 and 1997, respectively. He earned his Ph.D. in electrical engineering from Missouri S&T in 2000.
From 2000 to 2007, he worked for NCR Corp. as a consultant engineer, and in July 2007 he joined Missouri S&T.
His research interests include signal integrity and electromagnetic interference (EMI) designs in high-speed digital systems, DC power-bus modeling, intra-system EMI and radio frequency interference, printed circuit board noise reduction, differential signaling, and cable and connector designs.
Fan served as chair of the IEEE EMC Society TC-9 Computational Electromagnetics Committee from 2006 to 2008, and was a distinguished lecturer of the IEEE EMC Society in 2007 and 2008. He currently serves as chair of the Technical Advisory Committee of the IEEE EMC Society, and he is an associate editor for the IEEE Transactions on Electromagnetic Compatibility and EMC magazine. He received an IEEE EMC Society Technical Achievement Award in August 2009.
Fan’s department now has 10 IEEE Fellows out of 30 tenure and tenure track faculty.
Recognizing the achievements of its members is an important part of the IEEE’s mission. Each year, after a rigorous evaluation procedure, the IEEE Fellow Committee recommends a select group of recipients for elevation to IEEE Fellow. Fewer than 0.1 percent of voting members are selected annually.
