  • US Navy VHDL Modelling Guide

      This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) project. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL Data Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production data and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP project, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.

  • 基于MATLAB数字信号处理论文最终

    随着信息技术的不断发展,数字信号处理已成为一个极其重要的学科和技术领域,在通信、语音、图像、遥感、生物工程等众多领域得到了广泛的应用。数字信号处理的核心内容主要是信号的获取、传输和处理、识别及综合等。信号是信息的载体,系统是信息处理的手段。因此,为了更好的研究信号和系统的基本理论与方法,使同学们更好地理解和掌握数字信号处理的理论知识,在实验过程中,借助MATLAB这个平台来进行辅助设计。 MATLAB的GUIDE是专门用于图形用户界面的快速开发环境,本设计利用MATLAB的GUIDE工具箱制作了一套辅助“数字信号处理”课程教学的实验软件包。该实验软件包是由一系列形象的图形用户界面组成,每个界面以坐标窗口、弹出框、按键、动态文本框等为基本部分,构建了较为完善和友好的人机交互方式,使用便捷。该系统的形象直观,总体界面友好,具有开放性,便于学生对所学理论知识的理解,大大提高教学的效果和效率。 本文首先简要介绍了数字信号处理和MATLAB的相关知识,然后着重阐述了该实验软件包的组成及设计思路、方法,最后说明了软件的调试和测试过程。本教学实验软件包基本是按照国家十一五教材《数字信号处理(第3版)》(高西全,丁玉梅等)的编写思路进行总体设计的,整个构架包括六个核心部分:基本信号的产生、序列的基本运算、离散傅立叶变换、Z变换和逆Z变换、卷积运算和数字滤波器(IIR数字滤波器和FIR数字滤波器)的设计。较好的契合了教学内容,对理论课程的辅助效果明显。

  • 寄存器和环路滤波器的设计

    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.

  • 校准ADC内部偏移的光学微控制器DS4830

    Abstract: The DS4830 optical microcontroller's analog-to-digital converter (ADC) offset can change with temperature and gainselection. However, the DS4830 allows users to measure the ADC internal offset. The measured ADC offset is added to the ADCoffset register to nullify the offset error. This application note demonstrates the DS4830's ADC internal offset calibration in theapplication program.

  • 数字集成电路设计Digital Integrated Circuit Design

      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.

    第一章  传输线理论一  传输线原理二  微带传输线三  微带传输线之不连续分析第二章  被动组件之电感设计与分析一  电感原理二  电感结构与分析三  电感设计与模拟四  电感分析与量测传输线理论与传统电路学之最大不同,主要在于组件之尺寸与传导电波之波长的比值。当组件尺寸远小于传输线之电波波长时,传统的电路学理论才可以使用,一般以传输波长(Guide wavelength)的二十分之ㄧ(λ/20)为最大尺寸,称为集总组件(Lumped elements);反之,若组件的尺寸接近传输波长,由于组件上不同位置之电压或电流的大小与相位均可能不相同,因而称为散布式组件(Distributed elements)。 由于通讯应用的频率越来越高,相对的传输波长也越来越小,要使电路之设计完全由集总组件所构成变得越来越难以实现,因此,运用散布式组件设计电路也成为无法避免的选择。 当然,科技的进步已经使得集总组件的制作变得越来越小,例如运用半导体制程、高介电材质之低温共烧陶瓷(LTCC)、微机电(MicroElectroMechanical Systems, MEMS)等技术制作集总组件,然而,其中电路之分析与设计能不乏运用到散布式传输线的理论,如微带线(Microstrip Lines)、夹心带线(Strip Lines)等的理论。因此,本章以讨论散布式传输线的理论开始,进而以微带传输线为例介绍其理论与公式,并讨论微带传输线之各种不连续之电路,以作为后续章节之被动组件的运用。
