Abstract

This paper presents a novel three-input single-output current-mode universal biquadratic filter using only one voltage differencing current conveyor (VDCC) and three grounded passive components. The proposed circuit can realize low-pass (LP), band-pass (BP), high-pass (HP), band-stop (BS), and all-pass (AP) biquadratic functions. The natural angular frequency (ωo) and the quality factor (Q) can be tuned orthogonally by varying the circuit components. The proposed configuration has a low component count, low active and passive sensitivities and suitability to be integrated circuit implementation. PSPICE simulation results using TSMC 0.18 μm CMOS process parameters are included, which show good agreement with the theoretical predictions.
