Single FDCCII-based universal voltage-mode filter

A new versatile universal voltage-mode biquad with three inputs and five outputs using a single fully differential current conveyor, two grounded capacitors and three resistors is proposed. The proposed configuration can be used as either a single-input five-output filter or three-input two-output filter. It can simultaneously realize all five different generic filtering signals: lowpass, bandpass, highpass, bandstop and allpass, unlike the previously reported works. It still maintains the following advantages: (i) employs all grounded capacitors, (ii) there is no need to employ inverting-type input signals, (iii) uses orthogonal control of ω0 and Q, (iv) simultaneously realizes lowpass, bandpass, highpass, bandstop and allpass responses for the single-input five-output filter, and (v) no need to impose component choice to realize all five generic responses for the three-input two-output filter.
