巢湖学院2014届本科毕业论文（设计）共源级放大器的电路设计及版图实现摘要集成电路设计技术是现在信息时代的关键技术之一，当今的超大规模集成电路（VLSL）设计也已经离不开计算机辅助（CAD）。Tanner就是CAD软件的一种，它是由TannerResearch公司开发的基于windows平台的用于集成电路设计的工具软件，该软件功能强大，从电路设计、分析模拟到电路布局都可实现。本设计就是基于tanner软件实现共源级放大器的电路图设计及版图绘制。共源极放大器是CMOS电路中的基本增益级。它是典型的反向放大器，负载可以是有源负载或者电流源。共源极放大器需要得到比有源负载放大器更大的增益。设计电流源负载共源极放大器对学习了解IC有着本质的帮助和提高，这是理论与实践的相结合。本论文主要设计三种情况的放大器电路，他们是电阻负载共源级放大器、二极管连接的负载的共源级放大器和电流源负载共源级放大器电路，通过这三种放大器的设计能让我们更好的使用共源级放大器。关键词：共源级放大器；版图；TannerToolsI共源级放大器的电路设计及版图实现CircuitDesignandLayoutImplementationoftheDommon-sourceAmplifierAbstractICdesigntechnologyisnowoneofthekeytechnologiesoftheinformationage,today'sVLSI(VLSL)hasbeeninseparablefromcomputer-aideddesign(CAD).TannerisaCADsoftware,whichisbasedICdesignsoftwaretoolsforwindowsplatform,powerfulfunctionalityofthesoftwaredevelopedbytheTannerResearch,analogcircuitdesign,analysisofthecircuitlayoutcanberealized.Thisdesignisthecircuitdiagramtannercommonsourcesoftwarebasedamplifierdesignandlayoutdrawing.Isacommon-sourceamplifiercircuitofthebasicCMOSgainstage.Itisatypicalinvertingamplifier,ortheloadmaybeanactiveloadcurrentsource.Common-sourceamplifierneedstobegreaterthantheactiveloadamplifiergain.Designcurrentsourceloadcommon-sourceamplifierIChastolearntounderstandthenatureofthehelpandimprove,whichisacombinationoftheoryandpractice.Thisthesisamplifiercircuitdesignthreecases,theyareacommonsourceamplifierresistiveloadofsource-levelamplifierandacurrentsourcediodeconnectedloadoftheloadcommonsourceamplifiercircuit,amplifierdesignbythesethreemakeusmoreUsegoodcommonsourceamplifier.Keyword:CAD；TANNER；Common-sourceAmplifierII目录中文摘要....................................................................................................I英文摘要.....................................................................................................II引言...................................................................................................................11TANNERTOOLS软件简介...............................................................21.1TANNERTOOLS软件的组成........................................................21.2TANNERTOOLS设计综合流程.................................................32共源级放大器电路图和版图设计及其仿真42.1电阻负载共源级放大器电路原理分析.......42.1.1电阻负载共源级放大器电路图设计.......52.1.2电阻负载共源级放大器电路图SPICE文件设置............................................................................................................52.1.3电阻负载共源级放大器电路图仿真图62.1.4电阻负载共源级放大器版图设计..............72.1.5DRC规则检查.........................................................................72.1.6电阻负载共源级放大器版图spice文件设置...................................................................................................................82.1.7电阻负载共源级放大器版图仿真图.......82.2二极管连接负载的共源级放大器电路原理分析...............................................................
