Four new voltage-mode universal biquadratic filters each with one input terminal and five output terminals are presented.
Each of the first two proposed circuits uses four plus-type second-generation current conveyors, two grounded capacitors and
five resistors. The third proposed circuit employs two plus-type second-generation current conveyors, one differential voltage
current conveyor, two grounded capacitors and five resistors. The fourth proposed circuit employs two multi-output second-generation
current conveyors, two grounded capacitors and five resistors. Each of the proposed circuits can realize all the standard
filter functions; highpass, bandpass, lowpass, notch and allpass, simultaneously, without changing the passive elements. The
proposed circuits enjoy the features of orthogonal controllable of resonance angular frequencies and quality factors, using
only grounded capacitors as well as low active and passive sensitivities.
