This reference design (RD) features a fullyassembled and tested surface-mount printed circuitboard (PCB). The RD board utilizes the MAX48851:2 or 2:1 multiplexer and other ICs to implement acomplete video graphics array (VGA) 8:1multiplexer.VGA input/output connections are provided to easilyinterface the MAX4885 RD board with VGAcompatibledevices. The RD board gives the optionto use a single 5V DC power supply (V+), or this RDboard can be powered from any one of the eight VGA sources.

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.

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(jī)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(yùn)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

Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsiderations and general recommendations for choosing a 0.4mm- or 0.5mm-pitch WLP for yourapplication.

The LTP5900 includes sufficient power supply filtering and decoupling capacitancesuch that additional filtering should not be necessary for most battery-powereddesigns. Care must be taken to avoid large transient voltages on the supply as theM2510 steps up its current consumption (see the section on Supply Design below).
