如何使cir文件进行PSPice仿真当Orcad仿真库中找不到某些器件的时候，我们可以从这些器件的厂家网站上下载“.cir”格式的Spice Model，下面介绍一下如何使用这些“.cir”文件进行仿真。以AD620.cir为例：1.下载cir文件：从AD的网站上下载AD的cir格式文件，内容如下：由PSPice Library 文件生成Capture Lib文件（.olb）File->Export to capture part library…本案例中源文件为：CAOrCADIOrCAD_10.5New_Lib_Files\AD620XAD620.Lib本案例中目标文件为：C:\OrCAD\OrCAD_10.5\tools\capturelibrary\pspice\New_Models\AD620.olb在完成本操作后，就可以在Capture中使用AD620的库绘制需要仿真的原理图了。

Designing Boards with Atmel AT89C51,AT89C52, AT89C1051, and AT89C2051 for Writing Flash at In-circuit Test. Recent improvements in chips and testers have made it possible for the tester to begin taking over the role tradi-tionally assigned to the PROM program-mer. Instead of having a PROM pro- grammer write nonvolatile memories before assembling the board, the in-cir- cuit tester writes them during in-circuit testing operations. Many Teradyne Z18- series testers are now in use loading code into nonvolatile memories, micro- controllers and in-circuit programmable logic devices. The purpose of this note is to explain how the Z18 approaches the writing task for Atmel AT89C series IC’s, so that designers of boards using these chips can get the best results.

I saw the light of the future when I first read Ray Kurzweil’s best-seller book The Singularity Is Near: When Humans Transcend Biology. One cubic inch of nanotube cir- cuitry, once fully developed, would be up to one hundred million times more powerful than the human brain.

Recent advances in wireless communication technologies have had a transforma- tive impact on society and have directly contributed to several economic and social aspects of daily life. Increasingly, the untethered exchange of information between devices is becoming a prime requirement for further progress, which is placing an ever greater demand on wireless bandwidth. The ultra wideband (UWB) system marks a major milestone in this progress. Since 2002, when the FCC allowed the unlicensed use of low-power, UWB radio signals in the 3.1–10.6GHz frequency band, there has been significant synergistic advance in this technology at the cir- cuits, architectural and communication systems levels. This technology allows for devices to communicate wirelessly, while coexisting with other users by ensuring that its power density is sufficiently low so that it is perceived as noise to other users.

1.创建一个新项目：激活Design Manager，在菜单File中选择New Workspace，然后填入项目名称expl。2.输入网单文件：在Tools菜单中选择TextEdit，输入如下所示的网单文件。3.保存文件：将文件命名为expl.cir。4.对电路进行模拟：在Tools菜单中选择PspiceA/D，再在PspiceA/D的File菜单中选择Open，打开已保存过的输入文件expl.cir。5.检查出错：如果文件中出现了语法错误，PspiceA/D就会弹出错误提示框，并运行Message Viewer，告诉用户错误信息。如果输入文件没有语法错误，PspiceA/D就显示正确模拟的对话框，如图3-3类似，从图中可读出电路标题、元器件个数以及计算中所耗内存信息。6.查看输出文件：在File菜单中选择Examine 0utput，就可以通过Text Editor来浏览输出文件。输出文件中的各节点电压如下所示。由此可得出如下所示的静态工作点参数：Vw=2.9646V，Vow=7.1878-2.1919=4.9959V，Tg=Va/R.=2.1919/2.3=0.953mA。7.观察输出波形：在PspiceA/D的File菜单中选择Run Probe，或者在Design Manager 中选择Tools下的Probe，都可以调出Probe。Probe自动设置横坐标，纵坐标必须通过手动添加。在菜单Trace中选择Add，在Add Traces对话框的Trace Expression中输入V（6）/V（1），测量放大倍数。8.在Probe中，单击Plot菜单下的Add YAxis，增加一个新纵轴。9.单击Trace菜单下的Add，在Trace Expression中输入V（1）/I（V1），测量输入电阻，输出曲线如图2-2所示。
