先进的系统架构和集成电路设计技术，使得模数转换器 (ADC) 制造商得以开发出更高速率和分辨率，更低功耗的产品。这样，当设计下一代的系统时，ADC设计人员已经简化了很多系统平台的开发。例如，同时提高ADC采样率和分辨率可简化多载波、多标准软件无线电系统的设计。这些软件无线电系统需要具有数字采样非常宽频范围，高动态范围的信号的能力，以同步接收远、近端发射机的多种调制方式的高频信号。同样，先进的雷达系统也需要提高ADC采样率和分辨率，以改善灵敏度和精度。在满足了很多应用的具体需求，ADC的主要性能有了很大的提高的同时，ADC的功耗也有数量级的下降，进一步简化了系统散热设计和更小尺寸产品的设计。

This unique guide to designing digital VLSI circuits takes a top-down approach, reflecting the natureof the design process in industry. Starting with architecture design, the book explains the why andhow of digital design, using the physics that designers need to know, and no more.Covering system and component aspects, design verification, VHDL modelling, clocking, signalintegrity, layout, electricaloverstress, field-programmable logic, economic issues, and more, thescope of the book is singularly comprehensive.

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.

在 PCB 设计中，布线是完成产品设计的重要步骤，可以说前面的准备工作都是为它而做的， 在整个 PCB 中，以布线的设计过程限定最高，技巧最细、工作量最大。PCB 布线有单面布线、 双面布线及多层布线。布线的方式也有两种：自动布线及交互式布线，在自动布线之前， 可以用交互式预先对要求比较严格的线进行布线，输入端与输出端的边线应避免相邻平行， 以免产生反射干扰。必要时应加地线隔离，两相邻层的布线要互相垂直，平行容易产生寄生耦合。 目 录 高速 PCB 设计指南之一 高速 PCB 设计指南之二 PCB Layout指南(上) PCB Layout指南(下) PCB 设计的一般原则 PCB 设计基础知识 PCB 设计基本概念 pcb 设计注意事项 PCB 设计几点体会 PCB LAYOUT 技术大全 PCB 和电子产品设计 PCB 电路版图设计的常见问题 PCB 设计中格点的设置 新手设计 PCB 注意事项 怎样做一块好的 PCB 板 射频电路 PCB 设计 设计技巧整理 用 PROTEL99 制作印刷电路版的基本流程 用 PROTEL99SE 布线的基本流程 蛇形走线有什么作用 封装小知识 典型的焊盘直径和最大导线宽度的关系 新手上路认识 PCB 新手上路认识 PCB< ;二>
