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.

在模拟电路中的地线设计与数字电路中的地线设计,理论上要分开走,这样可以用不同标准的耦合电容去除,数字电路中的地线是DGND,模拟电路中的地线是AGND,而打磨三诺音箱中的功放部分,是典型的对模拟放大电路的打磨,因此功放中提到的地线就是AGND。

采用射频等离子体增强化学气相沉积(RF2PECVD)技术制备非晶硅(a2Si)NIP 太阳能电池,其中电池的窗口层采用P 型晶化硅薄膜,电池结构为Al/ glass/ SnO2 / N(a2Si :H) / I(a2Si :H) / P(cryst2Si : H) / ITO/ Al。为了使P 型晶化硅薄膜能够在a2Si 表面成功生长,电池制备过程中采用了H 等离子体处理a2Si 表面的方法。通过调节电池P 层和N 层厚度和H 等离子体处理a2Si 表面的时间,优化了太阳能电池的制备工艺。结果表明,使用H 等离子体处理a2Si 表面5 min ,可以在a2Si 表面获得高电导率的P 型晶化硅薄膜,并且这种结构可以应用到电池上;当P 型晶化硅层沉积时间12. 5 min ,N 层沉积12 min ,此种结构电池特性最好,效率达6. 40 %。通过调整P 型晶化硅薄膜的结构特征,将能进一步改善电池的性能。
