Hiroyuki Sakai

Hiroyuki Sakai (Senior Member, IEEE) received the B.S. and M.S. degrees in electrical engineering from Osaka University, Osaka, Japan, in 1984 and 1986, respectively, and the Ph.D. degree from the University of Fukui, Fukui, Japan, in 2020. In 1986, he joined the Semiconductor Research Center, Matsushita Electric Industrial Company Ltd., Osaka, and engaged in research and development of high-speed GaAs digital ICs, GaAs RF ICs for very compact cellular phones. In 1993, he started to research and develop millimeter-wave devices and their ICs, which resulted in the invention of a new millimeter-wave IC concept named millimeter-wave flip-chip IC (MFIC). From 1998 to 2000, he visited Stanford University, Stanford, CA, USA, as a Visiting Scholar, and expanded his research subjects to new Si-based RF devices and their integration technologies. From 2012 to 2017, he continued his research on mm-wave ICs based on GaAs, GaN, Si-BiCMOS, and CMOS LSI technologies at some laboratories of Panasonic Corporation. In 2020, he joined the Tokyo Institute of Technology, Tokyo, Japan, as a Creative Manager of Open Innovation Platform, where he is currently a Specially Appointed Professor of Electrical and Electronic Engineering. Prof. Sakai served as a Secretary for the IEEE Electron Devices Society Kansai Chapter from 2002 to 2003. He was a member of the Technical Program Committee of IEEE International Solid-State Circuit Conference (ISSCC) from 2002 to 2008.
