New current-mode current-controlled universal filter with single input andthree outputs

In this study, a new current-mode current-controlled universal filter with single input and three outputs is presented. The proposed circuit uses sing le-output current controlled conveyors (CCCIIs) and can simultaneously real ize lowpass, bandpass and highpass filter functions all at high impedance o utputs. Realization of notch and allpass responses does not require additio nal active elements. The circuit enjoys independent current-control of the parameters w(0) and w(0)/Q without disturbing the gains of the lowpass, ban dpass and highpass filters. Both its active and passive sensitivities are l ow.
