Joris Van Driessche received the M.Sc. degree in electrical engineering from the University of Ghent, Ghent, Belgium, in 2001. He joined imec in 2001 and worked as an RF Front-end Architecture Research Engineer with a main focus on system specification and architecture definition of multi-standard RF transceivers. In 2006, he became Project Manager on reconfigurable RF transceivers in the Wireless Department at imec, focusing on challenges towards true software defined radio transceivers optimized for advanced CMOS technologies. Currently, he is Program Manager for the 5G & beyond wireless communication research activities at imec addressing challenges for millimeter wave and sub-THz RFIC, antenna, packaging and system design.
Power-efficient Radio Architectures towards THz Communications
With the ever-increasing throughput requirements of communication systems and thanks to advances in semiconductor technology, carrier frequencies above 100 GHz are being investigated for high capacity applications such as advanced gaming, high-speed access hot-spots and point-to-point network links. Those frequencies offer very wide bandwidths and will exploit large antenna arrays. The corresponding architectures will significantly differ from traditional systems.
In this presentation, key challenges as well as solutions for above 100GHz radio architectures will be discussed including RF system and hardware architecture trade-offs, semiconductor technologies and circuits as well as antenna and packaging aspects.
