The Reactor design pattern handles service requests that are delivered concurrently to an application by one or more clients. Each service in an application may consist of serveral methods and is represented by a separate event handler that is responsible for dispatching service-specific requests.

Power conversion by virtue of its basic role produces harmonics due to theslicing of either voltages or currents. To a large extent the pollution in theutility supply and the deterioration of the power quality has been generatedor created by non-linear converters. It is therefore ironic that power convertersshould now be used to clean up the pollution that they helped to create inthe first place.In a utility system, it is desirable to prevent harmonic currents (which resultin EMI and resonance problems) and limit reactive power flows (whichresult in transmission losses).Traditionally, shunt passive filters, comprised of tuned LC elements andcapacitor banks, were used to filter the harmonics and to compensate forreactive current due to non-linear loads. However, in practical applicationsthese methods have many disadvantages.

Construction Strategy of ESD Protection CircuitAbstract： The principles used to construct ESD protection on circuits and the basic conceptions of ESD protection design are presented.Key words：ESD protection/On circuit, ESD design window, ESD current path1 引言靜電放電（ESD，Electrostatic Discharge）給電子器件環(huán)境會帶來破壞性的后果。它是造成集成電路失效的主要原因之一。隨著集成電路工藝不斷發(fā)展，互補金屬氧化物半導(dǎo)體（CMOS，Complementary Metal-Oxide Semiconductor）的特征尺寸不斷縮小，金屬氧化物半導(dǎo)體(MOS, Metal-Oxide Semiconductor)的柵氧厚度越來越薄，MOS 管能承受的電流和電壓也越來越小，因此要進一步優(yōu)化電路的抗ESD 性能，需要從全芯片ESD 保護結(jié)構(gòu)的設(shè)計來進行考慮。

模擬集成電路的設(shè)計與其說是一門技術(shù)，還不如說是一門藝術(shù)。它比數(shù)字集成電路設(shè)計需要更嚴(yán)格的分析和更豐富的直覺。嚴(yán)謹(jǐn)堅實的理論無疑是嚴(yán)格分析能力的基石，而設(shè)計者的實踐經(jīng)驗無疑是誕生豐富直覺的源泉。這也正足初學(xué)者對學(xué)習(xí)模擬集成電路設(shè)計感到困惑并難以駕馭的根本原因。.美國加州大學(xué)洛杉機分校(UCLA)Razavi教授憑借著他在美國多所著名大學(xué)執(zhí)教多年的豐富教學(xué)經(jīng)驗和在世界知名頂級公司(AT&T，Bell Lab，HP)卓著的研究經(jīng)歷為我們提供了這本優(yōu)秀的教材。本書自2000午出版以來得到了國內(nèi)外讀者的好評和青睞，被許多國際知名大學(xué)選為教科書。同時，由于原著者在世界知名頂級公司的豐富研究經(jīng)歷，使本書也非常適合作為CMOS模擬集成電路設(shè)計或相關(guān)領(lǐng)域的研究人員和工程技術(shù)人員的參考書。... 本書介紹模擬CMOS集成電路的分析與設(shè)計。從直觀和嚴(yán)密的角度闡述了各種模擬電路的基本原理和概念，同時還闡述了在SOC中模擬電路設(shè)計遇到的新問題及電路技術(shù)的新發(fā)展。本書由淺入深，理論與實際結(jié)合，提供了大量現(xiàn)代工業(yè)中的設(shè)計實例。全書共18章。前10章介紹各種基本模塊和運放及其頻率響應(yīng)和噪聲。第11章至第13章介紹帶隙基準(zhǔn)、開關(guān)電容電路以及電路的非線性和失配的影響，第14、15章介紹振蕩器和鎖相環(huán)。第16章至18章介紹MOS器件的高階效應(yīng)及其模型、CMOS制造工藝和混合信號電路的版圖與封裝。 1 Introduction to Analog Design 2 Basic MOS Device Physics 3 Single-Stage Amplifiers 4 Differential Amplifiers 5 Passive and Active Current Mirrors 6 Frequency Response of Amplifiers 7 Noise 8 Feedback 9 Operational Amplifiers 10 Stability and Frequency Compensation 11 Bandgap References 12 Introduction to Switched-Capacitor Circuits 13 Nonlinearity and Mismatch 14 Oscillators 15 Phase-Locked Loops 16 Short-Channel Effects and Device Models 17 CMOS Processing Technology 18 Layout and Packaging

Once relegated to the hinterlands of low cost indicatorlights, the LED is again in the spotlight of the lightingworld. LED lighting is now ubiquitous, from car headlightsto USB-powered lava lamps. Car headlights exemplifyapplications that capitalize on the LED’s clear advantages—unwavering high quality light output, tough-assteelrobustness, inherent high effi ciency—while a USBlava lamp exemplifi es applications where only LEDs work.Despite these clear advantages, their requirement forregulated voltage and current make LED driver circuitsmore complex than the venerable light bulb, but some newdevices are closing the gap. For instance, the LTM®8040μModule™ LED driver integrates all the driver circuitryinto a single package, allowing designers to refocus theirtime and effort on the details of lighting design criticalto a product’s success.

Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" off the road or making it to the nearest service station. Redundant systems, watchdog timers, and other controlcircuits are used to reroute signals and perform other functions that ensure that a vehicle can safely make it off the road when afailure occurs.
