Analysis of Polyphase Filter Section with CFAs

  • Published 2003


A new RC active polyphase filter section is presented. The section uses three conventional current feedback amplifiers (CFAs). The transfer function of the section has a single pole and optionally a single zero. With a cascade of this sections, any polyphase filter can be easily realized. The paper also introduces the leakage caused by element deviation and the effects of the amplifier in non-ideal case. Furthermore, non-ideal performances of the proposed filter section are tested with computer simulations. Key-Words: Analog filter, polyphase filter, CFA filter, leakage, mismatch, simulation
