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

无线通信中频段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信机。目前的多频段射频收发机是通过在同一基板上集成针对单个无线标准优化的多个硅组件核心，或者通过使用先进的封装技术机械地封装专门为单个无线标准定制的多个硅芯片组来实现的。这两种方法都代价高昂。此外，这些多频段射频收发器在应对无线通信中的任何新频段和新标准时，由于在重新配置方面的僵化，提供了零灵活性。深亚微米CMOS的速度使射频系统的发展成为可能，可以利用采样数据和数字信号处理技术来降低射频收发器的复杂性、降低成本、提高性能和增强适应性。该项目将由多伦多Ryerson大学的研究人员和渥太华Kaben Wireless Silicon Inc.的行业专家共同实施，以利用Ryerson大学的研究资源，包括经验丰富的研究人员、精力充沛和目标驱动的研究生，以及Kaben Wireless Silicon Inc.在无线通信方面的卓越记录，开发采用CMOS(互补金属-氧化物-硅)技术的低功率可重新配置电荷域射频前端组件核心，以满足日益增长的软件无线电需求。CRD项目的结果将使Kaben Wireless Silicon Inc.受益，该公司是用于无线通信的高性能射频组件核心的领先供应商。

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.
