A Top-Down Design Approach for Millimeter Wave SERDES Circuits

该集成系统方案的重点是为高速数据通信系统开发串行/反串行（SERDES）电路。最近设备方面的进展已经为太赫兹的应用打开了大门。仍然存在的一个困难是在信道上传输高速数据流。高速数据传输的关键部件是SERDES电路。SERDES输出数据的抖动必须比我们现在拥有的要低得多。预计从该项目中获得的一些结果也将对毫米波无线系统有益。知识优势：为了实现这一目标，提出了一种自上而下的方法，包括以下组件的集成和优化：(1)为毫米波混合信号应用开发各种高速串行/反串行设计技术，这些技术可能应用于未来的太赫兹应用；(2)无抖动和全对称复用/解复用器的设计，这将有助于减少许多通信系统中的抖动和相位噪声；(3)整个数字锁相环/锁相环组件的建模和仿真，以及可能有助于更快采集和增强降噪的压控振荡器电容器阵列；(4)应用深沟隔离共享技术，可显著减小布局面积和互连寄生。更广泛的影响：该项目的成功实施预计将显著有利于需要非常高吞吐量的高速数据通信系统，例如用于太赫兹成像和芯片对芯片通信的高速数据通信系统。它还将有利于许多其他重要的应用，如生物成像、射电天文学、高层大气研究和等离子体诊断。这些设计技术将被纳入计算机工程课程，也将被用于促进计算机工程领域，因为本系寻求招收高中学生，特别是女性和少数民族学生，并在整个本科学习中保留他们。

This integrative systems proposal focuses on developing serializer/deserializer (SERDES) circuit for high-speed data communication systems. Recent progress in devices has already opened the door for terahertz applications. One difficulty that remains is the transmission of high-speed data streams over the channel. A key-component for high-speed data transmission is the SERDES circuit. The jitter of the SERDES output data must be considerably lower than what we have now. It is expected that some of the results derived from this project will also be beneficial for millimeter wave wireless systems. Intellectual Merit: To achieve this goal, a top-down approach is proposed including the integration and optimization of the following components: (1) the development of various high-speed serializer/deserializer design techniques for millimeter wave mixed-signal applications that can possibly be applied to future terahertz applications; (2) the design of jitter free and fully symmetrical multiplexers/demultiplexers that will help reduce the jitter and phase noise in many communication systems; (3) the modeling and simulation of the entire digital-locked-loop/phased-locked-loop component, together with voltage-controlled oscillator capacitor arrays which may contribute to faster acquisition and enhanced noise reduction; (4) the application of the deep trench isolation sharing technique, which can significantly reduce the layout area and interconnect parasitic. Broader Impacts: The successful implementation of this project is anticipated to significantly benefit high speed data communication systems that require very high throughput, such as those used in terahertz imaging and chip-to-chip communications. It will also benefit a number of other important applications such as biological imaging, radio astronomy, upper atmosphere research, and plasma diagnostics. These design techniques will be incorporated into the Computer Engineering curriculum, and they will also be employed in promoting the field of computer engineering as the Department seeks to recruit high school students, especially women and minority students, and retain them throughout their undergraduate study.
