New lossless tunable floating FDNR simulation using two current conveyors and an INIC

Four new lossless tunable floating FDNR simulation circuits using two current conveyors (CCIIs) and a current-inversion negative immittance convertor (INIC) as active elements are proposed. The circuits have the following advantages: (i) use of only two CCIIs with the minimum number of passive elements; (ii) extremely low active sensitivities of realised FDNR; (iii) no requirements for component matching; (iv) tunability of the FDNR value through a single resistor; and (v) applicability for the simulation of higher-order immittance.
