Universal immittance function simulators using current conveyors

A new method for the realisation of parallel connection of inductance, capa citance and resistance using only positive type second-generation current c onveyors is presented. All circuits obtained using the proposed method exhi bit equivalent input admittance functions. For these circuits no element ma tching conditions are imposed, the simulated immittance values can orthogon ally be adjusted both for positive and negative values. The circuits employ only grounded passive components. The functionality of some of the circuit s is preserved at relatively high frequencies, illustrated bp simulation, a property which cannot be expected from classical voltage mode op-amps real isations.
