THE DESIGN OF A NOVEL LINEAR TRANSFORMATION SWITCHED-CAPACITOR FILTER

  • 摘要: 本文給出了一種利用線性變換設(shè)計(jì)開(kāi)關(guān)電容濾波器的新方法。它采用壓控電壓源等效變換,先修改原LC梯形濾波器,將其歸納為十六種基本節(jié),然后將線性變換擴(kuò)展到適用于含源和三端口情況,給出這十六種基本節(jié)對(duì)應(yīng)的開(kāi)關(guān)電容電路。用這十六種基本節(jié)可構(gòu)成全部四種類型濾波器低通、高通、帶通、帶阻濾波器。文中給出了它們的設(shè)計(jì)例子。一個(gè)N階濾波器只需要N個(gè)運(yùn)放,且無(wú)寄生電容影響。給出的三階橢圓低通和六階橢圓帶通的實(shí)驗(yàn)結(jié)果與理論分析相符。
    Abstract: A new method for switched-capacitor filleter (SCF) realization by using the linear transformation techique is described. It is shown that using VCVS equivalent transformation to revise the original LC ladder filter, sixteen basic sections are obtained. By using them, it is possible to realize all four kinds of filters-lowpass, highpass, bandpass and bandstop filter. As example, the paper presents their designs. A Nth order filter only requires N amplifiers and is insensitive to the parasitic capacitors. The experimental results of 3rd order lowpass and 6th order bandpass SCF are given and agree well with the theory.
