The future of mobile communication specified in 5G includes sub-6 GHz frequency bands, mm-Wave frequencies (28 GHz, 39 GHz) for very high throughput in enhanced Mobile Broadband, Ultra Reliable Low Latency Communications and Massive Machine Type Communication. This diversity including their specific challenges demands from RFIC designers to discover innovative architectures and smart techniques to enable novel products. This workshop will provide the community in-depth understanding of new and underlying concepts and systems in 5G, including the advantages and challenges of Massive MIMO and beam-forming, as well as RFIC design examples such as 5G mm-Wave circuits for transceivers and key building blocks.

The motivation of this workshop is to capture the lead-edge of IC design, what is the demand of the industry in the context of innovation in line with novel process technologies, as well, what are circuit and architectural concepts that are demanded. We focus especially on RFIC circuits design and technologies competing for today’s and tomorrow’s applications in 5G.

Title: Going from a 5G Vision to Real Implementation


Stretching beyond traditional mobile access, 5G is on a quest to transform connectivity as we know it today. With the ambition to provide data sharing anywhere at any time, for anyone and anything, the implementation challenges are demanding. This will also change the network deployment strategy and associated hardware realization in a profound way. On top, the spectrum availability has never been more diverse, which will further challenge traditional architectural approaches. This workshop presentation will highlight different 5G scenarios and their implications on the transceiver hardware. Transceiver block level requirements will be discussed, as well as tradeoffs in terms of building practice, antenna integration, and cost.

Title: Advanced Techniques for ADCs for 5G Massive-MIMO


Advanced Techniques for ADCs for 5G Receivers Abstract: In 5G systems, ADCs play a key role to increase the capacity and flexibility of the network. Depending on the system architecture, different scenarios result in different requirements for the ADCs. In handheld devices, focus is on low power design solutions and high bandwidths with moderate accuracy. In baseband stations, recent advances in technology and design techniques enable low-power Giga-sampled ADCs supporting direct-RF architectures. For massive MIMO systems, low-power, low-area solutions are needed to realize digital-intensive architectures. To accommodate for different use cases, flexible ADCs with e.g. a variable resolution are preferred. Design cases of ADCs suitable for high-performant 5G systems will be discussed.

Title: How Silicon Technology can address 5G IoT Challenges


With connectivity at the heart of industry transformation, 5G will have a key role to play—not just in the evolution of
communication but in the evolution of businesses and society as a whole. 5G is for example expected to support IoT deployment in order to become
an integral part of our economy and lifestyle, enabling to control more devices remotely in applications where real-time network performance is
Cellular network providers have already launched LTE network / chipset designed for IoT applications (Cat-M1) in order to support everything
from water monitoring systems, to asset trackers, and consumer electronics. Narrowband IoT (Cat-NB1) is the next generation Low Power
Wide Area (LPWA) technology currently under deployment and will be the foundation of NB-5G development. NB IoT has been designed to work
anywhere and can connect low-power devices to the mobile network. Cat-NB1 is optimized to handle infrequent data transfers, which makes it
ideal for devices that are deployed in remote locations and only need to transfer data every so often.
This presentation will review commercially available NB-IoT chipset solution and discuss how silicon technologies can help to address the three main 5G IoT challenges: price, coverage, and lower power consumption (with a special focus of RF and FEM integration).


Fred Gianesello received the B.S. and M.S. degree in Electronics Engineering from Institut national polytechnique de Grenoble (Grenoble, France) in 2003 and the Ph.D. degrees in electrical engineering from the Joseph Fourier University (Grenoble, France) in 2006. Dr Gianesello has authored and co-authored more than 150 refereed journal and conference technical articles. He has served on the TPC for the IEEE International SOI Conference from 2009 up to 2011, he is currently serving on the TPC for IEEE International Solid-State Circuits Conference and as reviewer for several conferences or journals. Dr Gianesello is currently working for STMicroelectronics in Crolles (France) as technical expert providing support to customer and performing business prospection for RF, mmW and optical products.
