Novel floating ideal tunable FDNR simulation using current conveyors

A novel active-RC circuit configuration for the realization of a floating admittance Y(s) = s^{2}D_{0} is proposed. The novelties of the scheme are realizability of ideal FDNR (D_{0}) 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 D_{0} by single resistor.
