Wireless communications is a multibillion dollar business. At the core of any wireless device is the high speed radio frequency integrated circuit which implements the radio transceiver. Radio frequency integrated circuits (RFICs) form some of the key enabling technologies for any wireless device from a cell phone to a wireless local area network, and global positioning systems along with many more. Intense research is still ongoing at the circuit level as improvements in radios are necessary to make RFICs more compatible with digital technologies, and provide lower power operation for longer battery life and at the same time increasing radio performance in order to deliver higher data rates to the user. One of the key components necessary to designing a high performance radio necessary to meet the demands of new wireless applications is the front end module which contains filters which make up the duplexor. These filters are responsible for isolating the receiver and transmitter and protecting the sensitive receiver from being bombarded with a wide spectrum of powerful and potentially damaging energy. Currently these filters are implemented as costly off chip passive components. The research in this proposal aims at replacing these filters with a completely integrated N-path filter technology which will provide a much smaller and cost effective solution to this problem. Skyworks Solutions has identified N-Path filters as a key enabling technology going forward. They are keenly interested in incorporating these filters into their front end modules. These filters also provide the opportunity to perform channel selection at RF due to the ability to reenter them at will. This will lead to new improved architectures for the radios they interface with that will enable better performance to meet the ever increasing needs of more advanced radios. This grant will support research to improve the performance of N-Path filters through the development of novel circuits aimed at increasing their performance capabilities. The proposed project will help to ensure ongoing Canadian information technology research in wireless communication providing employment for scientists and engineers.

无线通信是一项数十亿美元的业务。任何无线设备的核心是实现无线电收发器的高速射频集成电路。射频集成电路（RFICS）构成了从手机到无线局域网的任何无线设备的一些关键启用技术，以及全球定位系统以及更多的全球定位系统。激进的研究仍在电路级别进行，因为需要改进的收音机以使RFIC与数字技术更加兼容，并为更长的电池寿命提供较低的功率操作，同时提高无线电性能，以便向用户提供更高的数据速率。设计高性能无线电以满足新无线应用要求所需的高性能无线电所需的关键组件之一是前端模块，该模块包含构成双工的过滤器。这些过滤器负责隔离接收器和发射器，并保护敏感的接收器免于被各种强大且潜在破坏的能量轰炸。目前，这些过滤器被实施为昂贵的芯片被动组件。该提案中的研究旨在用完全集成的N径滤波器技术代替这些过滤器，该技术将为此问题提供更小且具有成本效益的解决方案。 Skyworks Solutions已将N路径过滤器确定为促进技术的关键技术。他们对将这些过滤器纳入其前端模块非常感兴趣。由于能够随意重新进入，这些过滤器还提供了在RF进行频道选择的机会。这将导致与他们接口的无线电的新架构，这将使更好的性能满足更高级无线电的不断增长的需求。该赠款将支持研究，以通过开发旨在提高其性能能力的新型电路来提高N路径过滤器的性能。拟议的项目将有助于确保正在进行的无线通信中正在进行的加拿大信息技术研究，从而为科学家和工程师提供就业。
