Body Biasing in 28nm UTBB FD-SOI CMOS Technology – a Device Approach to enable 5G RFICs
Mirjana Videnović-Mišić focuses on "Body Biasing in 28nm UTBB FD-SOI CMOS Technology – a Device Approach to enable 5G RFICs". As wireless networks are transitioning to 5G, there is a high demand for innovative wideband transceivers that will support growing number of bands in an area and cost efficient manner. Stringent system level requirements, new application scenarios together with continuing downscaling and voltage supply decrease impose novel design methodologies and use of innovative semiconductor technologies like 28nm UTBB FD SOI CMOS.
In her presentation, Mirjana Videnović-Mišić will explain biasing technique advantage given to a mixer-first receiver design from the device perspective. Area and circuit complexity reduction will be achieved for class A and class AB amplifiers while keeping a tight control over important figures of merit in all process corners.
Very high Data-rate RF Systems for beyond 5G
In his talk, Gernot Hueber is going to concentrate on "Very high Data-rate RF Systems for beyond 5G". Research projects in the mmWave/RF domain are targeting technical innovations for beyond 5G future wireless communication networks, developing specific backhaul/fronthaul applications operating in the 300 GHz frequency bands. Bitrates exceeding 100 Gb/s, cost-efficiency and high spectrum and power efficiency are the main features of the next generation RF-frontends that will be enabled by the key technologies developed in Silicon Austria Labs. System topologies and RF-components will be the key elements within the development envisaged.
A scalable and modular system architecture including packaging will enable cost-effective mass production of 300 GHz lens array antenna front-ends. The parallelization of data streams using multiplexing architectures such as line-of-sight MIMO, frequency carrier aggregation and polarization multiplexing will boost energy- and spectral efficiency. Furthermore, novel beam alignment concepts by using agile lens antennas allows automatic adjustments during life time, resulting in a significant reduction of installation/maintenance cost. By considering the design of the complete architecture, from antenna down to baseband, a high performance system is guaranteed as research outcome.
In this talk, beyond 5G scenarios will be considered: backhaul (point-to-point), fixed wireless access (point-to-multipoint), and access networks in crowded scenarios (point-to-multipoint). Demonstrations addressing these three scenarios will clearly show the powerful and flexibility of the targeted sub-mmW communication platforms.
