Abstract
A voltage-controlled oscillator (“VCO”) structure includes a plurality of VCO circuits, each having a different nominal operating frequency range. Power consumption of the VCO structure is regulated by selective activation/deactivation of the individual VCO circuits. In a preferred embodiment, only one of the VCO circuits is active at any given time. The active VCO can be selected to satisfy the requirements of the particular application and/or to compensate for semiconductor manufacturing process variations.
