This book is intended for the graduate or advanced undergraduate engineer. The primary motivation for developing the text was to present a complete tutorial of phase-Locked loops with a consistent notation. I believe this is critical for the practicing engineer who uses the text as a self-study guide.

The MAX2870 ultra-wideband phase-Locked loop (PLL) and voltagecontrol oscillator (VCO) can operate in both integer-N and fractional-Nmodes, similar to the Analog Devices ADF4350 wideband synthesizer.This application note compares the MAX2870 and ADF4350 registers andloop filter design in detail. Users who already familiar with ADF4350 canuse this application note as a quick design reference.

Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) products use crystal oscillators to generate areference for the phase-Locked loop (PLL)-based local oscillator (LO). This tutorial provides a basic description of theISM-RF Crystal Calculator, which can be used to calculate various impacts on crystal frequency accuracy and startupmargin for such an LO.

模拟集成电路的设计与其说是一门技术,还不如说是一门艺术。它比数字集成电路设计需要更严格的分析和更丰富的直觉。严谨坚实的理论无疑是严格分析能力的基石,而设计者的实践经验无疑是诞生丰富直觉的源泉。这也正足初学者对学习模拟集成电路设计感到困惑并难以驾驭的根本原因。.美国加州大学洛杉机分校(UCLA)Razavi教授凭借着他在美国多所著名大学执教多年的丰富教学经验和在世界知名顶级公司(AT&T,Bell Lab,HP)卓著的研究经历为我们提供了这本优秀的教材。本书自2000午出版以来得到了国内外读者的好评和青睐,被许多国际知名大学选为教科书。同时,由于原著者在世界知名顶级公司的丰富研究经历,使本书也非常适合作为CMOS模拟集成电路设计或相关领域的研究人员和工程技术人员的参考书。... 本书介绍模拟CMOS集成电路的分析与设计。从直观和严密的角度阐述了各种模拟电路的基本原理和概念,同时还阐述了在SOC中模拟电路设计遇到的新问题及电路技术的新发展。本书由浅入深,理论与实际结合,提供了大量现代工业中的设计实例。全书共18章。前10章介绍各种基本模块和运放及其频率响应和噪声。第11章至第13章介绍带隙基准、开关电容电路以及电路的非线性和失配的影响,第14、15章介绍振荡器和锁相环。第16章至18章介绍MOS器件的高阶效应及其模型、CMOS制造工艺和混合信号电路的版图与封装。 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

Telecommunication, satellite links and set-top boxes allrequire tuning a high frequency oscillator. The actualtuning element is a varactor diode, a 2-terminal device thatchanges capacitance as a function of reverse bias voltage.1 The oscillator is part of a frequency synthesizingloop, as detailed in Figure 1. A phase Locked loop (PLL)compares a divided down representation of the oscillatorwith a frequency reference. The PLL’s output is levelshifted to provide the high voltage necessary to bias thevaractor, which closes a feedback loop by voltage tuningthe oscillator. This loop forces the voltage controlledoscillator (VCO) to operate at a frequency determined bythe frequency reference and the divider’s division ratio.

常用的嵌入式处理器有ARM、MIPS、PowerPC、X86、68K/Cold fire等,MIPS是Microprocessor without Inter-Locked Pipeline Stages的缩写,是由MIPS技术公司开发的一种处理器内核标准。目前有32位和64位MIPS芯片。PowerPC是早期Motorola公司和IBM公司联合为Apple公司的MAC机开发的CPU芯片,商标权同时属于IBM和Motorola两家公司,并一度成为他们的主导产品。X86系列处理器起源于Intel架构的8080,然后发展出286、386、486直到现在的奔腾处理器乃至双核处理器等。从嵌入式市场来看,486DX也应该是和ARM、68K、MIPS和SuperH齐名的5大嵌入式处理器之一。Motorola 68K是出现比较早的一款嵌入式处理器,采用的是CISC结构。

DDR SDRAM控制器的VHDL源代码,含详细设计文档。 The DDR, DCM, and SelectI/O™ features in the Virtex™ -II architecture make it the perfect choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock Manager (DCM) provides the required Delay Locked Loop (DLL), Digital Phase Shift (DPS), and Digital Frequency Synthesis (DFS) functions. This application note describes a controller design for a 16-bit DDR SDRAM. The application note and reference design are enhanced versions of XAPP200 targeted to the Virtex-II series of FPGAs. At a clock rate of 133 MHz, 16-bit data changes at both clock edges. The reference design is fully synthesizable and achieves 133 MHz performance with automatic place and route tools.
