Millimeter-wave high-datarate wireless communication using beamforming (Piet Wambacq)
In the past ten years, the speed increase of CMOS thanks to the downscaling in the past ten years, together with the allocation of unlicensed spectrum around 60 GHz, has given rise to much research worldwide on mm-wave IC design in CMOS. The frequency band between 57 GHz and 66 GHz is intended for high datarate wireless communication using RF bandwidths of more than 1 GHz. The commercial deployment of mm-wave ICs takes more time than expected, partially due to the design challenges caused by the high operating frequency, which is more than ten times higher than the commercial ICs for the most widely used wireless communication standards, which operate below 6 GHz. To relax the high path loss at mm-wave frequencies in the link budget of wireless transceivers, these transceivers contain, next to the classical functionality of radios, beamforming functionality. This talk will explain the basics of beamforming together with several implementations of the beamforming control in the analog part of the transceivers. Further, most important bottlenecks of mm-wave radio architectures such as phase noise and power efficiency are addressed and several solutions are discussed. 
About the speaker:
Piet Wambacq  received the M.Sc. degree in electrical engineering and Ph.D. degree from the Katholieke Universiteit Leuven, Leuven, Belgium, in 1986 and 1996, respectively. He joined IMEC, Leuven, Belgium in  1996 as a Principal Scientist and he is now a Distinguished Member of Technical Staff, working on IC design in various technologies for wireless applications. Since 2000 he is a Professor with the Vrije Universiteit Brussel (VUB), Brussels, Belgium. He has authored or co-authored three books and more than 250 papers in edited books, international journals and conferences. He has been an associate editor of the IEEE Transactions on Circuits and Systems - Part 1 from 2002 to 2004. He was the co-recipient of the Best Paper Award at the Design, Automation and Test Conference (DATE) in 2002 and 2005, the EOS/ESD Symposium in 2004 and the Jan Van Vessem Award" for "Outstanding European Paper" at ISSCC 2015. He was a member of the program committee of the DATE conference from 2000 to 2007. He currently chairs the RF subcommittee of ISSCC and of ESSCIRC. He is a senior member of IEEE and Distinguished Lecturer of The Solid-State Circuits Society of IEEE.
