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.

Radio Frequency IntegrATed Circuit Design I enjoyed reading this book for a number of reasons. One reason is thAT itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog integrATed circuit designers in the past workedon applicATions AT low enough frequency thAT microwave issues did not arise.As a consequence, they were adept AT lumped parameter circuits and often notcomfortable with circuits where waves travel in space. However, in order todesign radio frequency (RF) communicATions integrATed circuits (IC) in thegigahertz range, one must deal with transmission lines AT chip interfaces andwhere interconnections on chip are far apart. Also, impedance mATching isaddressed, which is a topic thAT arises most often in microwave circuits. In mycareer, there has been a gap in comprehension between analog low-frequencydesigners and microwave designers. Often, similar issues were dealt with in twodifferent languages. Although this book is more firmly based in lumped-elementanalog circuit design, it is nice to see thAT microwave knowledge is brought inwhere necessary.Too many analog circuit books in the past have concentrATed first on thecircuit side rATher than on basic theory behind their applicATion in communicATions.The circuits usually used have evolved through experience, without asATisfying intellectual theme in describing them. Why a given circuit works bestcan be subtle, and often these circuits are chosen only through experience. Forthis reason, I am happy thAT the book begins first with topics thAT require anintellectual approach—noise, linearity and filtering, and technology issues. Iam particularly happy with how linearity is introduced (power series). In therest of the book it is then shown, with specific circuits and numerical examples,how linearity and noise issues arise.

IntegrATed EMI/Thermal Design forSwitching Power SuppliesWei ZhangThesis submitted to the Faculty of theVirginia Polytechnic Institute and StATe Universityin partial fulfillment of the requirements for the degree of IntegrATed EMI/Thermal Design forSwitching Power SuppliesWei Zhang(ABSTRACT)This work presents the modeling and analysis of EMI and thermal performancefor switch power supply by using the CAD tools. The methodology and design guidelinesare developed.By using a boost PFC circuit as an example, an equivalent circuit model is builtfor EMI noise prediction and analysis. The parasitic elements of circuit layout andcomponents are extracted analytically or by using CAD tools. Based on the model, circuitlayout and magnetic component design are modified to minimize circuit EMI. EMI filtercan be designed AT an early stage without prototype implementATion.In the second part, thermal analyses are conducted for the circuit by using thesoftware Flotherm, which includes the mechanism of conduction, convection andradiATion. Thermal models are built for the components. Thermal performance of thecircuit and the temperATure profile of components are predicted. Improved thermalmanagement and winding arrangement are investigATed to reduce temperATure.In the third part, several circuit layouts and inductor design examples are checkedfrom both the EMI and thermal point of view. Insightful informATion is obtained.

This document provides practical, common guidelines for incorporATing PCI Express interconnect layouts onto Printed Circuit Boards (PCB) ranging from 4-layer desktop baseboard designs to 10- layer or more server baseboard designs. Guidelines and constraints in this document are intended for use on both baseboard and add-in card PCB designs. This includes interconnects between PCI Express devices locATed on the same baseboard (chip-to-chip routing) and interconnects between a PCI Express device locATed “down” on the baseboard and a device locATed “up” on an add-in card ATtached through a connector. This document is intended to cover all major components of the physical interconnect including design guidelines for the PCB traces, vias and AC coupling capacitors, as well as add-in card edge-finger and connector considerATions. The intent of the guidelines and examples is to help ensure thAT good high-speed signal design practices are used and thAT the timing/jitter and loss/ATtenuATion budgets can also be met from end-to-end across the PCI Express interconnect. However, while general physical guidelines and suggestions are given, they may not necessarily guarantee adequATe performance of the interconnect for all layouts and implementATions. Therefore, designers should consider modeling and simulATion of the interconnect in order to ensure compliance to all applicable specificATions. The document is composed of two main sections. The first section provides an overview of general topology and interconnect guidelines. The second section concentrATes on physical layout constraints where bulleted items AT the beginning of a topic highlight important constraints, while the narrATive thAT follows offers additional insight.

A light-emitting diode (LED) is a semiconductor device thAT emits narrow-spectrum incoherent light when forward-biased.The color of the emitted light depends on the chemical composition of the semiconductor mATerial used, and can benear-ultraviolet, visible or infrared. LEDs are more prevalent today than ever before, replacing traditional incandescent andfluorescent bulbs in many lighting applicATions. Incandescents use a heATed filament, are subject to breakage and burnoutand operATe AT a luminous efficiency of 2% to 4%. Fluorescents are more efficient, AT 7% to 12%, but require highdrive voltage and contain mercury, a toxic substance thAT may be eventually banned in certain countries. LEDs, however,produce light directly through electroluminescence, operATe AT low voltage and can deliver over 20% luminous efficiency.

Abstract: This applicATion note illustrATes an intermediATe 8V switching power supply for an automotive radio and infotainment system.The design withstands the complete automotive input voltage range (including cold crank and load dump conditions), assuring a stable8V supply for common subsystems such as a CD driver, LCDs, and a radio module in modern infotainment systems. To avoiddisturbance in the AM and FM bands, the switching power supply runs AT a fixed frequency of 2MHz, enabling an ideal solution forradio systems.

ATX是计算机的工作电源，作用是把交流220V的电源转换为计算机内部使用的直流5V，12V，24V的电源。 ATX电源的特点:与AT电源相比，ATX电源增加了“＋3.3V、＋5VSB、PS－ON ”三个输出。其中“＋3.3V”输出主要是供CPU用，而“＋5VSB”、“PS－ON”输出则体现了ATX电源的特点。ATX电源最主要的特点就是，它不采用传统的市电开关来控制电源是否工作，而是采用“＋5VSB、PS－ON”的组合来实现电源的开启和关闭，只要控制“PS－ON”信号电平的变化，就能控制电源的开启和关闭。“PS－ON”小于1V伏时开启电源，大于4.5伏时关闭电源。
