A new current-mode current-controlled universal filter is proposed. The circuit uses four single-output current controlled conveyors (CCCIIs) and two grounded capacitors and can simultaneously realize lowpass, bandpass and highpass responses. The circuit enjoys independent control of the parameters omega(0) and omega(0)/Q by adjusting the bias currents of the CCCIIs, without disturbing the gains of the lowpass, bandpass and highpass responses. No component matching is required and both its active and passive sensitivities are low. SPICE simulation results are given to confirm the theoretical analysis.
