Abstract

A configuration for realizing a 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 ω₀ and the quality factor Q and low active and passive sensitivities. PSPICE simulation results are employed to verify the circuit performance
