Özet

In this study, a voltage mode, multi input single output type multifunction biquad is proposed. It uses only one operational transresistance amplifier (OTRA) as the active element, while previously reported voltage mode multifunction filters require more OTRAs. Proposed multi input single output type biquad configuration can realize all five different filter transfer functions. Theoretical results are verified with PSPICE simulations using a CMOS realization of OTRA.
