A Top-Down Design Approach for Millimeter Wave SERDES Circuits

该综合系统方案的重点是开发用于高速数据通信系统的串行器/解串器(SERDES)电路。设备的最新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。高速数据传输的一个关键部件是SERDES电路。SERDES输出数据的抖动必须比我们现在拥有的低得多。预计该项目得出的一些结果也将有益于毫米波无线系统。智能优点：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)开发各种可能应用于未来太赫兹应用的毫米波混合信号应用的高速串行器/解串器设计技术；(2)设计有助于降低许多通信系统中的抖动和相位噪声的无抖动和完全对称的多路复用器/解复用器；(3)对整个数字锁定环/锁相环组件以及压控振荡器电容器阵列进行建模和仿真，这可能有助于更快地捕获和增强噪声降低；(4)深槽隔离共享技术的应用，可以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使需要非常高吞吐量的高速数据通信系统显著受益，例如用于太赫兹成像和芯片到芯片通信的系统。它还将有益于其他一些重要的应用，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，并将用于促进计算机工程领域，因为该系寻求招收高中生，特别是女性和少数族裔学生，并将他们保留到本科阶段。

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.
