在國內(nèi)Protel軟件一直大受歡迎，從DOS時(shí)代的Protel3.3(Autotrax 1.61)到現(xiàn)在具有EDA Client/Server （客戶/服務(wù)器）即C/S“框架”體系結(jié)構(gòu)的Protel98，它始終是PCB設(shè)計(jì)和制造領(lǐng)域的大眾化工具軟件，成為電子設(shè)計(jì)工作者們的首選。 在規(guī)范化的設(shè)計(jì)管理中，設(shè)計(jì)文件圖樣必須遵守相應(yīng)的國家標(biāo)準(zhǔn)，如《電子產(chǎn)品圖樣繪制規(guī)則》、《設(shè)計(jì)文件管理制圖》和《印制板制圖》等，而由于Protel軟件都是英文版，因此無法直接打印出符合國家標(biāo)準(zhǔn)的圖紙，要將圖紙規(guī)范化常用的方式是套打，即先將符合國家標(biāo)準(zhǔn)的表和漢字等打在紙上，再將該紙放入打印機(jī)，用Protel軟件將印制板圖打印其上，形成符合標(biāo)準(zhǔn)的文件，但這種做法效率很低，而且圖形常會(huì)打偏，有時(shí)甚至?xí)蚍矗?jīng)筆者試驗(yàn)，找到了一種簡便的方法，使印制板圖轉(zhuǎn)換為AUTOCAD格式，再在AUTOCAD里一次性打印出符合標(biāo)準(zhǔn)的圖紙。

Specifying the Right reference and applying it correctly isa more difficult task than one might first surmise, consideringthat references are only 2- or 3-terminal devices.Although the word “accuracy” is most often spoken inreference to references, it is dangerous to use this wordtoo freely because it can mean different things to differentpeople. Even more perplexing is the fact that a referenceclassified as a dog in one application is a panacea inanother. This application note will familiarize the readerwith the various aspects of reference “accuracy” andpresent some tips on extracting maximum performancefrom any reference.

Avalanche photodiodes (APDs) are widely utilized in laserbased fiberoptic systems to convert optical data intoelectrical form. The APD is usually packaged with a signalconditioning amplifier in a small module. An APD receivermodule and attendant circuitry appears in Figure 1. TheAPD module (figure Right) contains the APD and a transimpedance(e.g., current-to-voltage) amplifier. An opticalport permits interfacing fiberoptic cable to the APD’sphotosensitive portion. The module’s compact constructionfacilitates a direct, low loss connection between theAPD and the amplifier, necessary because of the extremelyhigh speed data rates involved
