项目摘要
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The objective of this research is to investigate a new class of mm-wave phase-locked loops (PLLs) for ultra-wide bandwidth applications. Current mm-wave PLLs are based on injection-locked frequency dividers, which have many locking limitations that affect their operating range. These limitations translate to limited data rate communications, and low resolution in imaging and spectroscopy applications. This work proposes a fundamental change in the design of mm-wave phase locked loops, combining the functions of the oscillator and injection-locked frequency divider through the use of N-push operation. The intellectual merit of this proposal is manifested in its goal of developing new circuit techniques for mm-wave applications that efficiently utilize the wide bandwidth available and lends itself to operation at even higher frequency at the mm-wave/THz boundary. The proposed approach is expected to achieve an order of magnitude improvement in the phased-locked-loop operation range and simplify the design of the fundamental oscillator and the selection process of the frequency divider.A successful effort will provide the scientific community with design and optimization techniques for novel PLL topologies with superior performance compared to traditional architectures. The proposed approach can be employed for stable, wideband electronic-based THz sources having numerous applications including radio astronomy, atmospheric sensing, biological research, wireless communications, radar, and chemical and explosives detection. Undergraduate students will be involved in the experimental work. Planned outreach activities include developing hands-on activities for "Design your Future Day," an annual workshop organized for female high school students.
该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。本研究的目标是研究一种新型的毫米波锁相环(PLL)的超宽带应用。当前的毫米波PLL基于注入锁定分频器,其具有影响其操作范围的许多锁定限制。这些限制转化为有限的数据速率通信,以及成像和光谱应用中的低分辨率。本文提出了一种毫米波锁相环设计的根本改变,通过N推操作将振荡器和注入锁定分频器的功能结合起来。该提案的智力价值体现在其开发用于mm波应用的新电路技术的目标中,该新电路技术有效地利用了可用的宽带宽,并使其在mm波/THz边界处以甚至更高的频率运行。该方法有望将锁相环的工作范围提高一个数量级,简化基频振荡器的设计和分频器的选择过程,为科学界提供新的PLL拓扑结构的设计和优化技术,使其具有比传统结构更优越的上级性能。所提出的方法可以用于稳定的宽带电子基太赫兹源,具有许多应用,包括射电天文学,大气传感,生物研究,无线通信,雷达,以及化学和爆炸物检测。本科生将参与实验工作。计划开展的外联活动包括为“设计你的未来日”开展实践活动,这是一个为女高中生组织的年度讲习班。
