Monolithic microwave active inductors have been used to realize very narrow X-band tunable filters. The active inductors were used in local feedback configurations. This results in simple structures that make optimal use of the unloaded resonator quality factor. MMIC band pass and band stop filters were designed, realized and fully characterized.
