A single input and three outputs voltage-mode biquadratic filter using three plus-type second-generation current conveyors (CCII), two grounded capacitors and five resistors is presented. The proposed circuit offers the following features: realization of three filter functions, which are, lowpass, bandpass and notch filters, simultaneously, the use of only grounded capacitors. PSPICE simulation results are also included.
