In contrast to the previously known circuits which require two to four op-amps, current conveyors (CC) or operational mirrored amplifiers (OMAs) to realise a floating negative impedance converter, the Letter presents a configuration for realising a floating generalised negative impedance converter/inverter (GNIC/GNII) which employs no more than a single OMA along with a minimum of three passive components (without requiring any passive-component-matching). An application example is demonstrated. The workability of the proposed structures has been confirmed by SPICE simulations.
