The voltage-mode with triple-input single-output universal biquad filter using DURCs and CCCIIs

This article presents a new voltage-mode with triple-input single-output universal biquad filter using double capacitive layers uniformly distributed RC lines (DURCs) and a second-generation current-controlled current conveyors (CCCIIs). The proposed universal biquad filter has possesses three inputs and single output for generate four filter types as low-pass filter (LPF), high-pass filter (HPF), band-pass filter (BPF) and notch filter (NF) in voltage responses, employs the minimum active and passive components and also provides low active and passive sensitivities at frequency cutoff in all realize filter. The property of the proposed circuit is simulation using PSPICE to verify the theory.
