Keynote Speech 1: New Challenges and Opportunities in the Development of Millimeter-wave Front-End Modules for 5G Wireless Communication Equipment

Prof. Nicolas Constantin

École de technologie supérieure (ÉTS), Canada

Abstract:

Mobile devices for fifth generation (5G) wireless communication will be required to operate at millimeter-wave frequencies with complex antenna structures; to be energy efficient; to enable very high speed data transmission; to allow versatility in their applications; and to use highly integrated electronic technologies. The multi-IC (Integrated Circuits) millimeter-wave transmitter front-end section, including power amplifiers, will play a critical role to achieve this. Research on energy efficiency and linearity improvement approaches has shown a remarkable progress over the last two decades, from basic dynamic biasing and load switching in early 3G CDMA devices to advanced Doherty architectures and Envelope Tracking in 4G LTE devices, but is encountering dramatically increased challenges on the 5G roadmap. These recent trends are proving to be questionable, to the very least, in the context of multiple antennas for beamforming and Multiple-Input- Multiple-Output (MIMO) architectures, compounded by significantly higher losses at millimeter-wave frequencies (28 GHz, 60 GHz) and the large bandwidth requirements (ranging from few hundred MHz to well above 1 GHz). In addition, the perspective of more versatile functional capabilities in the mobile devices, such as interfacing with millimeter-wave identification devices (MMIDs) and other ultra-low-power RF/millimeter-wave devices, adds to the complexity of the front-end circuits. These new challenges come with exciting and new research opportunities, requiring a new look into the use of software-assisted hardware reconfiguration for efficiency improvement, digital signal processing for linearity improvement and embedded calibration.

Keynote Speech 3: Integrated Wireless Senors: A Hardware Perspective

Prof. Khaled Nabil Salama

King Abdullah University of Science and Technology, Saudi Arabia

Abstract:

Networked systems of tiny wireless and sensing-enabled devices continue to give birth to a host of new applications that range from medical sensors for image-guided surgery, to distributed image-based surveillance of remote areas for security or environmental reasons. Such applications mandate new requirements in terms of size of the devices as well as the bandwidth required. Extreme requirements for small size packaging of the devices are obvious for many applications including biomedical ones. Fully integrated sensor modules that are capable of harvesting energy, sensing the environment and communicating with other sensors or base stations are becoming a necessity. Despite the development chips for these systems, there continues to be a need for improved implementations of micro-scale detection and processing systems for further convenience, scaling and portability. These systems would include a sensor module (mostly in mems), attached to analog front end circuitry, an analog to digital converter and a wireless communication module. We will present the research conducted at KAUST addressing many of these components. A flagship project demonstrating these concept is a single chip implantable wireless sensor system for Intraocular Pressure Monitoring (IOPM). This system-on-chip (SoC) is battery free and harvests energy from incoming RF signals, consumes 513 W of peak power and when implanted inside the eye, it can communicate over a distance of more than 15 cm.
