A novel active current conveyor (CC II)-RC realisation of a floating admittance function Y(s) = s2D corresponding to an ideal FDNR element is reported. The scheme has the following advantages: (i) use of only two capacitors and a resistor; (ii) extremely low active sensitivities; (iii) single-resistor tunability of D; (iv) no design constraint involving component matching; (v) realisability of ideal FDNR even with nonideal CC II devices.
