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.

无线通信中频带和标准的激增促使学术界和工业界寻找能够适应广泛的无线标准和未来标准的可重新配置的无线收发器。本发明的多频带射频收发器通过在同一衬底上集成针对单独无线标准优化的多个硅组件核心或通过使用先进封装技术机械地封装专门针对单独无线标准定制的多个硅芯片组来实现。这两种方法都很昂贵。此外，这些多频带RF收发器由于其重新配置的刚性而在应对无线通信中的任何新频带和新标准方面提供零灵活性。深亚微米CMOS的速度使得RF系统能够以这样的方式发展，即采样数据和数字信号处理技术可以用于减轻复杂性、降低成本、提高性能并增强RF收发器的适应性。该项目将由多伦多瑞尔森大学的研究人员和卡本无线硅公司的工业专家联合开展，渥太华，利用瑞尔森大学的研究资源，包括经验丰富的研究人员、充满活力和目标驱动的研究生，以及Kaben Wireless Silicon Inc.的卓越记录。在无线通信领域，开发采用CMOS（互补金属氧化物硅）技术的低功耗可重构电荷域射频前端组件内核，以满足对软件定义无线电日益增长的需求。CRD项目的成果将使Kaben Wireless Silicon Inc.受益，无线通信用高性能射频元件核心的领先供应商。
