Two new basic topologies for the realization of second-generation current conveyor (CCII)-based floating immitance function simulators are presented. Using these circuits, a given real, rational and stable current transfer function of minimum phase can be converted into a floating immitance simulator without any critical-component matching requirement. These topologies make possible the derivation of very useful basic floating immitances as well as high-order general floating. immitances in a systematic way. Finally, simulation and experimental results are given to verify the theoretical analysis.
