Abstract
A configuration for realizing current-mode second-order multifunctional filter using four-terminal floating nullors (FTFNs) is presented in this paper. The proposed filter consists of three multiple-output FTFNs and passive grounded elements. The circuit can simultaneously realize the highpass, bandpass and lowpass current transfer functions from the same configuration, orthogonal control of the natural angular frequency ωo and the quality factor Q and low active and passive sensitivities. PSPICE simulation results are employed to verify the circuit performance.
