NOVEL UNIVERSAL RC-ACTIVE FILTERS USING DVCC ELEMENTS

Josef Čajka - Kamil Vrba

   A new voltage-mode universal biquad and its adjoint current-mode universal biquad using two differential-voltage current conveyors are proposed. Both biquads enjoy the following advantages: realization of highpass, bandpass, lowpass, notch and allpass filtering, canonical transfer functions ensuring low sensitivities, and minimal number of passive elements.

Keywords: current conveyors, universal filters
