Charge-Domain filtering and digitization techniques for reconfigurable radio-frequency transceivers

点击翻译按钮获取中文摘要

The proliferation of bands and standards in wireless communications has motivated both academia and industry to search for reconfigurable wireless transceivers that can adapt to a broad range of wireless standards and future standards. Present multi-band radio-frequency transceivers are realized either by integrating multiple silicon component cores optimized for individual wireless standard on the same substrate or by packaging multiple silicon chipsets specifically tailored for individual wireless standard mechanically using advanced packaging technologies. Both approaches are costly. In addition, these multi-band RF transceivers provide zero flexibility in coping with any new band and new standard in wireless communications due to their rigidness in reconfiguration. The speed of deep-submicron CMOS has enabled RF systems to be developed in such a way that sampled-data and digital signal processing techniques can be utilized to alleviate complexity, reduce cost, improve performance, and enhance adaptability of RF transceivers. This project will be jointly carried out by researchers from Ryerson University, Toronto, and industrial experts from Kaben Wireless Silicon Inc., Ottawa, to take the advantage of the research resources of Ryerson University including experienced researchers, energetic and goal-driven graduate students, and the track record of excellence of Kaben Wireless Silicon Inc. in wireless communications to develop low-power reconfigurable charge-domain radio-frequency front-end component cores in CMOS (Complementary Metal-Oxide-Silicon) technology to meet the increasing demand for software-defined radio. The outcome of the CRD project will benefit Kaben Wireless Silicon Inc., a leading supplier of high-performance radio-frequency component cores for wireless communications.
