Abstract
A current-controlled current-mode biquadratic filter using a modified type of a four-terminal floating nullor (FTFN), which is called as an electronically tunable multiple-output FTFN (ET-FTFN), is proposed. The proposed filter with two-input and three-output terminals comprises only ET-FTFNs and four grounded passive elements. The filter can simultaneously realize the inverting-type lowpass, noninverting-type lowpass, inverting-type banpass, noninverting-type bandpass, highpass, bandstop and allpass filter functions. The natural angular frequency and the quality factor are independently controlled by adjusting the external bias currents of the ET-FTFNs. All the active and passive sensitivities are low. PSPICE simulation results are employed to verify the circuit performance. © 2006 ICASE.
