  • 射频集成电路设计John Rogers(Radio Freq

    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.

  • 阻抗匹配

    阻抗匹配  阻抗匹配(Impedance matching)是微波电子学里的一部分,主要用于传输线上,来达至所有高频的微波信号皆能传至负载点的目的,不会有信号反射回来源点,从而提升能源效益。  大体上,阻抗匹配有两种,一种是透过改变阻抗力(lumped-circuit matching),另一种则是调整传输线的波长(transmission line matching)。  要匹配一组线路,首先把负载点的阻抗值,除以传输线的特性阻抗值来归一化,然后把数值划在史密夫图表上。  把电容或电感与负载串联起来,即可增加或减少负载的阻抗值,在图表上的点会沿著代表实数电阻的圆圈走动。如果把电容或电感接地,首先图表上的点会以图中心旋转180度,然后才沿电阻圈走动,再沿中心旋转180度。重覆以上方法直至电阻值变成1,即可直接把阻抗力变为零完成匹配。  由负载点至来源点加长传输线,在图表上的圆点会沿著图中心以逆时针方向走动,直至走到电阻值为1的圆圈上,即可加电容或电感把阻抗力调整为零,完成匹配.........
