Abstract: A new second-generation current conveyor (CCII)-based voltage-mode biquadratic filter with one input terminal and five output terminals has been presented. The proposed circuit uses four plus-type CCIIs, two grounded capacitors and five resistors and it is suitable for implementation with the now available integrated circuit (IC). The proposed circuit can realize all the standard filter functions; high-pass, band-pass, low-pass, notch and all-pass, simultaneously, without changing the passive elements. The proposed circuit enjoys the features of high input impedance, orthogonal controllable of resonance angular frequency and quality factor, using only grounded capacitors as well as low active and passive sensitivities. The feasibility of the proposed configuration has been demonstrated by practical results.
