Cascadable Voltage-Mode Multifunction Biquad Employing Single OTRA
نویسنده
چکیده
Abstract – A voltage-mode (VM), multi-input single-output (MISO) type multifunction biquad is proposed. It uses only one operational transresistance amplifier (OTRA) as the active element, while previously reported VM multifunction filters require more OTRAs. Proposed MISO type biquad configuration can realize all five different filter transfer functions. Theoretical results are verified with PSPICE simulations using a CMOS realization of OTRA.
