Novel floating ideal tunable FDNR simulation using current conveyors

Abstract

A novel active-RC circuit configuration for the realization of a floating admittance <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Y(s) = s^{2}D_{0}</tex> is proposed. The novelties of the scheme are realizability of ideal FDNR <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">(D_{0})</tex> element using only two resistors and a capacitor, use of second-generation current conveyors (CC II) as the active elements which offer extremely low active sensitivites, no design constraint involving component matching, and tunability of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">D_{0}</tex> by single resistor.
