DVCC-based current-mode IAFs without parasitic effects

摘要

This paper introduces current-mode inverse active filters (IAFs) employing differential voltage current conveyors (DVCCs) and grounded passive components without the effect of parasitic resistances. The IAFs enable inverse low-pass (ILP), inverse band-pass (IBP) and inverse high-pass (IHP) responses by adding the circuit current outputs suitably. Additionally the circuit parameters ω0 and Q can be set orthogonally adjusting the circuit passive components. The IAFs enjoy very low sensitivities to the circuit components. An achievement example is given together with simulation results by PSPICE.
