Novel positive current output DVCC-based biquadratic circuit

This paper introduces a novel biquadratic circuit using only positive current output differential voltage current conveyors. The biquadratic circuit enables low-pass, bandpass, high-pass, band-stop and all-pass responses by the selections and additions of the input and output currents without any component matching constraints. Moreover the circuit parameters ω0 and Q can be set orthogonally adjusting the circuit passive components, Achievement example is given together with simulation responses by PSPICE.
