Abstract

In this paper new tunable, monolithic active resonator topologies are presented. The circuits, based on the advances in GaAs MMIC active inductors, show stable, high-Q performance with large tunability and compact layout. The simulated results exceed significantly the properties of conventional varactor-tuned circuits. The new circuits are applied to active filters and proposed active resonator oscillators (ARO), which show great potential for wireless applications at the 2 GHz band.<>
