项目摘要
Objective: The objective of this research is to develop innovative radio receiver architectures and circuits with a goal to significantly improve the trade-off between power-efficiency and interference-handling capability in radio front-ends. The approach is based on low-power front-end architectures such as recursive receivers and techniques for adaptive interference cancellation and linearization. A key focus of the research will be on receivers for wireless systems with multi-mode and multi-band functionality.Intellectual Merit: The research will include a detailed investigation of approaches to significantly alleviate the dynamic range constraint in the analog front-ends of wireless receivers implemented in short-channel complementary metal-oxide-semiconductor (CMOS) processes. Through the use of techniques such as feedforward linearization and interference cancellation, these constraints will be addressed prior to signal digitization in the receiver, while minimizing the use of external passive filters, in order to help facilitate integration of wireless transceivers in future generations of CMOS processes. A receiver architecture based on these approaches will be implemented in a 130nm or similar short-channel CMOS process.Broader Impacts: The agile radio front-end architectures developed as part of this research are expected to impact several current and future wireless systems for diverse end-applications such as biomedical, communications and computing. The research and training program will involve student researchers at the graduate and undergraduate levels, and include students from underrepresented groups. Research results will be used to update courses, and will be disseminated through publications, seminars and websites.
目的:本研究的目的是开发创新的无线电接收机架构和电路,目标是显着提高无线电前端的功率效率和干扰处理能力之间的权衡。该方法基于低功耗前端架构,例如递归接收机以及自适应干扰消除和线性化技术。该研究的一个重点将是具有多模式和多频段功能的无线系统接收器。知识产权:该研究将包括详细研究显着减轻短通道互补金属氧化物半导体(CMOS)工艺中实现的无线接收器模拟前端动态范围限制的方法。通过使用前馈线性化和干扰消除等技术,这些约束将在接收器中的信号数字化之前得到解决,同时最大限度地减少外部无源滤波器的使用,以帮助促进无线收发器在未来几代CMOS工艺中的集成。基于这些方法的接收器架构将在130 nm或类似的短通道CMOS process.Broader影响:敏捷的无线电前端架构开发作为本研究的一部分,预计将影响几个当前和未来的无线系统的各种终端应用,如生物医学,通信和计算。研究和培训计划将涉及研究生和本科生级别的学生研究人员,并包括来自代表性不足群体的学生。研究结果将用于更新课程,并将通过出版物、研讨会和网站传播。
