THE DESIGN OF DIFFERENTIATOR BASED SWITCHED- CURRENT HIGH-PASS LADDER FILTERS

  • 摘要: 本文應(yīng)用一種新型的雙線性/前饋差分器(BFD)來設(shè)計(jì)開關(guān)電流(SI)高通梯形濾波器。這種BFD是用本文提出的SI模塊,通用差分器(GD)構(gòu)成的,此GD具有多種差分功能。文中按S域頻帶變換和Z域帶變換分別介紹了兩種不同的設(shè)計(jì)方法,還給出了Chebyshev高通濾波器和橢圓(Elliptic)高通濾波器設(shè)計(jì)的實(shí)例。
    Abstract: This paper deals with the design of switched-current (SI) high-pass ladder filters using a novel bilinear/feed-forward differentiator (BFD). The BFD is based on SI modular block, the generalized differentiator(GD) proposed in this paper. Various differential functions can be performed by the GD. Two different design techniques employing S domain and Z domain frequency transformations are described respectively. Examples of Chebyshev and Elliptic high-pass filters are also given.
