Abstract

A new current-mode universal biquadratic filter with three inputs and one output is presented. The proposed filter based on only two multi-output second-generation current controlled conveyors (MO-CCCII), two grounded capacitors and two grounded resistors, can realize five standard filter functions of high-pass, band-pass, low-pass, notch and all-pass from the same configuration. The simulated natural frequency f0 31.8KHz of the filter can be tuned electronically by adjusting the bias currents of the MO-CCCIIs, No critical matching conditions are required for all the filter response realizations. The performance of the proposed biquadratic filter was examined by PSPICE simulation.
