Three new current-mode second-order filter configurations which employ one or two current controlled conveyors (CCCIIs) and three passive elements are presented. Each proposed filter can realize one of the bandpass, lowpass or highpass responses all at high impedance outputs. The proposed filters offer current-control of pole angular frequency omega(0) without disturbing the parameter sigma(0)/Q. No component matching is required and all the passive and active sensitivities are low. SPICE simulation results are given to confirm the theoretical analysis.
