Abstract

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