In this thesis, a new voltage-mode universal biquadratic filter with one-input and six-outputs is presented. The proposed circuit use two differential voltage current conveyors (DVCCs), two grounded capacitors and four resistors and offers the following features: the realization of all the standard filter functions, that is, high-pass, band-pass, low-pass, notch, and all-pass filters, simultaneously, orthogonal control of ωo and Q, the use of only grounded capacitors, low active and passive sensitivities.
