在许多消费电子产品及白色家电应用中，新兴的电容感应按钮正作为一个流行的用户界面替代机械开关。然而，电容感应界面设计也会带来挑战，在新产品研发、生产及质量控制等方面都可能会出现问题。例如，不同线路板的电容感应按钮寄生电容(CP )可能不同，环境变化（例如温度及湿度）也可能会改变CP。系统不同噪声也不相同。

以某高速实时频谱仪为应用背景，论述了5 Gsps采样率的高速数据采集系统的构成和设计要点，着重分析了采集系统的关键部分高速ADC（analog to digital，模数转换器）的设计、系统采样时钟设计、模数混合信号完整性设计、电磁兼容性设计和基于总线和接口标准（PCI Express）的数据传输和处理软件设计。在实现了系统硬件的基础上，采用Xilinx公司ISE软件的在线逻辑分析仪（ChipScope Pro）测试了ADC和采样时钟的性能，实测表明整体指标达到设计要求。给出上位机对采集数据进行处理的结果，表明系统实现了数据的实时采集存储功能。

高速数字系统设计下载pdf:High-Speed Digital SystemDesign—A Handbook ofInterconnect Theory and DesignPracticesStephen H. HallGarrett W. HallJames A. McCallA Wiley-Interscience Publication JOHN WILEY & SONS, INC.New York • Chichester • Weinheim • Brisbane • Singapore • TorontoCopyright © 2000 by John Wiley & Sons, Inc.speeddigital systems at the platform level. The book walks the reader through everyrequired concept, from basic transmission line theory to digital timing analysis, high-speedmeasurement techniques, as well as many other topics. In doing so, a unique balancebetween theory and practical applications is achieved that will allow the reader not only tounderstand the nature of the problem, but also provide practical guidance to the solution.The level of theoretical understanding is such that the reader will be equipped to see beyondthe immediate practical application and solve problems not contained within these pages.Much of the information in this book has not been needed in past digital designs but isabsolutely necessary today. Most of the information covered here is not covered in standardcollege curricula, at least not in its focus on digital design, which is arguably one of the mostsignificant industries in electrical engineering.The focus of this book is on the design of robust high-volume, high-speed digital productssuch as computer systems, with particular attention paid to computer busses. However, thetheory presented is applicable to any high-speed digital system. All of the techniquescovered in this book have been applied in industry to actual digital products that have beensuccessfully produced and sold in high volume.Practicing engineers and graduate and undergraduate students who have completed basicelectromagnetic or microwave design classes are equipped to fully comprehend the theorypresented in this book. At a practical level, however, basic circuit theory is all thebackground required to apply the formulas in this book.
