Wireless communications has become a field of enormous scientific and economic interest. Recent success stories include 2G and 3G cellular voice and data services (e.g., GSM and UMTS), wireless local area networks (WiFi/IEEE 802.11x), wireless broadband access (WiMAX/IEEE 802.16x), and digital broadcast systems (DVB, DAB, DRM). On the physical layer side, traditional designs typically assume that the radio channel remains constant for the duration of a data block. However, researchers and system designers are increasingly shifting their attention to channels that may vary within a block. In addition to time dispersion caused by multipath propagation, these rapidly time-varying channels feature frequency dispersion resulting from the Doppler effect. They are, thus, often referred to as being “doubly dispersive.”

My association with the theory of controls in continuous time started during my studies at the Indian Institute of Technology, Kharagpur, India, in 1974 as an undergraduate student in the Controls and Power program. The initial introduction by Professors Kesavamurthy, Y. P. Singh, and Rajagopalan laid the foundation for a good basic understanding of the subject matter. This pursuit and further advanced study in the field of digital controls continued during my days as a graduate student in the Electrical and Systems Engineering Department at the University of Connecticut in Storrs, from 1983 to 1988.

原版英文PDF電子書免費下載：Digital Integrated Circuit Design From VLSI Architectures to CMOS Fabrication，891頁 本書從架構和算法講起，介紹了功能驗證、vhdl建模、同步電路設計、異步數據獲取、能耗與散熱、信號完整性、物理設計、設計驗證等必備技術，還講解了vlsi經濟運作與項目管理，并簡單闡釋了cmos技術的基礎知識，全面涵蓋了數字集成電路的整個設計開發(fā)過程。 本書既可以作為高等院校微電子、電子技術等相關專業(yè)高年級師生和研究生的參考教材，也可供半導體行業(yè)工程師參考。 現代電子系統日益復雜，隨著半導體工藝水平的提高，單芯片的集成度和功能得以不斷增強，其設計復雜度和各種風險也隨之變大，甚至影響到投資者對研發(fā)新的更復雜系統芯片的信心。但是，為了有效降低便攜式移動系統的產品單位成本和能量消耗，同時為了在產品獨特性方面有競爭力，越來越多的電子產品仍然必須采用專用芯片解決方案。因此，深入了解數字集成電路設計的基本方法和關鍵問題，并明確開發(fā)過程的各個實踐環(huán)節(jié)存在的風險，就變得十分必要。 本書是一本將超大規(guī)模數字電路基本概念原理與工程實踐管理相結合的綜合性教材。作者根據自己多年的教學和工程實踐經驗，從工程實踐的關鍵問題出發(fā)，對超大規(guī)模數字電路的全部講授內容進行了一次全新的梳理，形成了清晰的解決思路。在數字集成電路設計的各個環(huán)節(jié)，作者重點闡述了設計研制中必須考慮的關鍵因素，在豐富經驗基礎上對設計中常常出現的問題進行了詳盡的討論，可以幫助研究生和資深工程師完善自身的設計經驗和能力，也可以幫助項目管理者明確各個環(huán)節(jié)的工作重點，規(guī)避研發(fā)環(huán)節(jié)的風險。 本書和其他數字集成電路教科書相比，有兩個突出的特點。第一是自頂向下的組織方式，從算法的架構設計開始，討論了同步設計的各種時鐘技術、設計驗證、散熱和封裝問題，還討論了VLSI（超大規(guī)模集成電路）經濟學與項目管理。讀者可以根據自身需要直接閱讀感興趣的章節(jié)，而不需要很多半導體物理與器件方面的知識。第二是實用性。本書用了相當多的篇幅討論了工程實踐的問題，例如給出了一個很好的設計數據組織方法，還有很多檢查列表與提醒。 在目前的集成電路項目里，大量使用了重用的虛擬元件，通常有十幾個到幾十個時鐘，驗證工作量也要占到整個項目周期和投資的50%~70%，關于虛擬元件、時鐘方案、VLSI經濟學、項目管理、功能驗證、設計驗證等內容的討論都可以直接作為實際項目實踐的參考。總之，本書的內容相當全面并有一定深度，基本涵蓋了數字集成電路設計的各個方面，非常適合用作學習數字集成電路設計的高年級本科生與研究生的教科書，也適合作為正在從事數字集成電路開發(fā)的工程人員的參考書。

In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.

Abstract: This application note describes how sampling clock jitter (time interval error or "TIE jitter") affectsthe performance of delta-sigma digital-to-analog converters (DACs). New insights explain the importanceof separately specifying low-frequency (< 2x passband frequency) and high-frequency or wideband (> 2xpassband frequency) jitter tolerance in these devices. The article also provides an application example ofa simple highly jittered cycle-skipped sampling clock and describes a method for generating a properbroadband jittered clock. The document then goes on to compare Maxim's audio DAC jitter tolerance tocompetitor audio DACs. Maxim's exceptionally high jitter tolerance allows very simple and low-cost sampleclock implementations.

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.

Control systems are becoming increasingly dependent on digital processing and so require sensors able to provide direct digital inputs. Sensors based on time measurement, having outputs based on a frequency or phase, have an advantage over conventional analogue sensors in that their outputs can be measured directly in digital systems by pulse counting.
