All digital frequency synthesizers: phase 2

无线通信是一项价值数十亿美元的国际业务。任何无线设备的核心都是实现无线电收发信机的高速射频集成电路。射频集成电路(RFIC)构成了从手机到无线局域网、全球定位系统(GPS)、物联网(IOT)等任何无线设备的一些关键使能技术。电路层面的密集研究仍在进行中，因为有必要改进无线电，使RFIC与数字技术更兼容，并为更长的电池寿命提供更低的功率操作，同时提高无线电性能，以便向用户提供更高的数据速率(例如5G无线网络)。频率合成器是设计高性能无线电以满足新的无线应用需求所必需的关键部件之一。频率合成器负责生成将高频RF信号转换回可由数字信号处理器恢复的较低频率所需的基准。MicroSemi公司已将频率合成器确定为未来的关键使能技术。他们对新的改进的体系结构非常感兴趣，这种体系结构将使性能更好，以满足更先进的无线电日益增长的需求。此外，他们正在寻找与数字互补金属氧化物半导体(CMOS)工艺更兼容的新架构。这笔赠款将支持所有数字频率合成器通过开发旨在提高其性能能力的新电路来提高其性能的研究。拟议的项目将有助于确保加拿大正在进行的无线通信信息技术研究，为科学家和工程师提供就业机会。

Wireless communications is a multibillion dollar international 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, global positioning systems (GPS), the internet of things (IOT) and 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 (for example 5G wireless networks). One of the key components necessary to designing a high performance radio necessary to meet the demands of new wireless applications is the frequency synthesizer. The frequency synthesizer is responsible for generating the reference needed to translate high frequency RF signals back to lower frequencies where the data can be recovered by the digital signal processor. Microsemi Corporation has identified the frequency synthesizer as a key enabling technology going forward. They are keenly interested in new improved architectures that will enable better performance to meet the ever increasing needs of more advanced radios. Additionally they are seeking new architectures which will be more compatible with digital complementary metal oxide semiconductor (CMOS) processes. This grant will support research to improve the performance of all digital frequency synthesizers 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.
