Radio Frequency Integrated Circuit Design I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog integrated circuit designers in the past workedon applications at low enough frequency that microwave issues did not arise.As a consequence, they were adept at lumped parameter circuits and often notcomfortable with circuits where waves travel in space. However, in order todesign radio frequency (RF) communications integrated circuits (IC) in thegigahertz range, one must deal with transmission lines at chip interfaces andwhere interconnections on chip are far apart. Also, impedance matching isaddressed, which is a topic that arises most often in microwave circuits. In Mycareer, there has been a gap in comprehension between analog low-frequencydesigners and microwave designers. Often, similar issues were dealt with in twodifferent languages. Although this book is more firmly based in lumped-elementanalog circuit design, it is nice to see that microwave knowledge is brought inwhere necessary.Too many analog circuit books in the past have concentrated first on thecircuit side rather than on basic theory behind their application in communications.The circuits usually used have evolved through experience, without asatisfying intellectual theme in describing them. Why a given circuit works bestcan be subtle, and often these circuits are chosen only through experience. Forthis reason, I am happy that the book begins first with topics that require anintellectual approach—noise, linearity and filtering, and technology issues. Iam particularly happy with how linearity is introduced (power series). In therest of the book it is then shown, with specific circuits and numerical examples,how linearity and noise issues arise.

Altium Designer 10是由Altium公司推出的一款開發(fā)軟件，Altium Designer 10綜合了電子產(chǎn)品一體化開發(fā)所需的所有必須技術(shù)和功能。Altium Designer 在單一設(shè)計環(huán)境中集成板級和FPGA系統(tǒng)設(shè)計、基于FPGA和分立處理器的嵌入式軟件開發(fā)以及PCB版圖設(shè)計、編輯和制造。并集成了現(xiàn)代設(shè)計數(shù)據(jù)管理功能,使得Altium Designer成為電子產(chǎn)品開發(fā)的完整解決方案－一個既滿足當前，也滿足未來開發(fā)需求的解決方案。 Altium Designer10 為您帶來了一個全新的管理元 Altium Designer release 10器件的方法。其中包括新的用途系統(tǒng)、修改管理、新的生命周期和審批制度、實時供應鏈管理等更多的新功能! Altium Designer 10安裝流程： 安裝完后復制 AD10.Crack 文件夾下文件到安裝目錄。 1.運行AD10KeyGen，點擊“打開模板”，加載license.ini，如想修改注冊名，只需修改：TransactorName=Your Name，其中Your Name用你自己的名字替換，其它參數(shù)在單機版的情況下無需修改； 2.點擊“生成協(xié)議”，保存生成的alf文件(文件名任意，如“jack ”)，并將其放到你的安裝目錄下； 3.將patch.exe放到你的安裝目錄下，運行patch，對安裝目錄下的dxp.exe文件補丁，注意運行破解時軟件沒有運行； 4.啟動DXP，運行菜單DXP->My Account，點擊Add Standalone License file，加載前面生成的license（.alf）文件后即能正常使用了。 資源是.bin格式的鏡像文件，到網(wǎng)上下一個UltraISO打開后另存為iso或isz格式，用DAEMON Tools Lite虛擬光驅(qū)打開就能安裝了。(或者安裝一個快壓打開) 安裝提醒： 安裝時有兩個路徑選擇，第一個是安裝主程序的；第二個是放置設(shè)計樣例、元器件庫文件、模板文件的，共3.3GB。如果你的C盤留的不夠大，建議將3GB多的東西和主程序安裝在一塊兒。 安裝完成后界面可能是英文的，如果想調(diào)出中文界面，則可以：DXP-->Preferences-->System-->General-->Localization--選中Use localized resources，保存設(shè)置后重新啟動程序就有中文菜單了。 Altium Designer 10破解方法： 安裝包里已經(jīng)帶有破解文件了，但沒有AD10KeyGen這個文件，所以要把注冊名改成自己的名字不方便。 1.運行AD10KeyGen，點擊“打開模板”，加載license.ini，如想修改注冊名，只需修改： TransactorName=Your Name 其中Your Name用你自己的名字替換，其它參數(shù)在單機版的情況下無需修改； 2.點擊“生成協(xié)議”，保存生成的alf文件(文件名任意，如“jack ”)，并將其放到你的安裝目錄下； 3.將patch.exe放到你的安裝目錄下，運行patch，對安裝目錄下的dxp.exe文件補丁，注意運行破解時軟件沒有運行； 4.啟動DXP，運行菜單DXP->My Account，點擊Add Standalone License file，加載前面生成的license（.alf）文件后即能正常使用了。 注意： 1.局域網(wǎng)內(nèi)用同一license不再提示沖突 2.僅供學習研究使用，勿用于非法用途。 相關(guān)資料：altium designer 10 破解教程
