Noël Deferm (S'09) was born in Diest, Belgium, in 1985. In 2008 he received the degree of M.S. in Electrical Engineering (ir.) from the Katholieke Universiteit Leuven (K.U.Leuven), Belgium. The subject of his MS thesis was on the design of ultra low-power architectures for wireless sensor networks.He is currently working as a postdoc researcher at the MICAS laboratories of the department of Electrical Engineering (ESAT) of the Katholieke Universiteit Leuven (K.U.Leuven) from which he received the Ph.D. in Engineering Science (dr.) in 2014. While working towards his Ph.D. degree, his main research focus was on mm-wave CMOS circuit design for wireless communication systems.In 2011, he received the TSMC-Europractice innovation award.Patrick Reynaert was born in Wilrijk, Belgium, in 1976. He received the Master of Industrial Sciences in Electronics (ing.) from the Karel de Grote Hogeschool, Antwerpen, Belgium in 1998 and both the Master of Electrical Engineering (ir.) and the Ph.D. in Engineering Science (dr.) from the KU Leuven), Belgium in 2001 and 2006 respectively.From 2001 to 2006, he was a Teaching and Research Assistant within the MICAS research group of the Department of Electrical Engineering (ESAT), K.U.Leuven, Belgium. While working towards his Ph.D. degree, his main research focus was on CMOS RF power amplifiers and analog circuit design for mobile and wireless communications. From 2001 to 2006, he was also a Lector at ACE-Group T Leuven, Belgium were he teached several undergraduate courses on electronic circuit design.During 2006-2007, he was a post-doctoral researcher at the Department of Electrical Engineering and Computer Sciences of the University of California at Berkeley. At the Berkeley Wireless Research Center, he was working on mm-wave CMOS integrated circuits within the group of Prof. Ali Niknejad. For this research, he received a Francqui Foundation fellowship from the Belgian AmericanEducational Foundation.During the summer of 2007, he was a visiting researcher at Infineon, Villach, Austria where he worked on the linearization of basestation power amplifiers.Since October 2007, he is a Professor at the Katholieke Universiteit Leuven, department of Electrical Engineering (ESAT) and a staff member of the ESAT-MICAS research group. His main research interests include mm-wave CMOS circuit design and RF power amplifiers.Patrick Reynaert is a Senior Member of the IEEE, member of the ESSCIRC TPC, member of the IEDM TPC, chair of the IEEE SSCS Benelux Chapter, co-chair of the Analog, Mixed-signal and RF working group of the Global Semiconductor Alliance and member of the Commission on Innovation Policy of the Flemish Council for Science and Innovation (VRWI).In 2011, he received the TSMC-Europractice innovation award. In 2011-2012, he served as the Guest Editor for the IEEE Journal of Solid-state Circuits Special Issue on ESSCIRC 2011.
