Abstract: In one embodiment, an apparatus includes a voltage controlled oscillator (VCO) to output an oscillating signal. The VCO may have a tank formed of at least one capacitor coupled in parallel with at least one inductor, and a plurality of transconductors to provide energy to the tank. At least one of the plurality of transconductors can be controllably switched to be coupled to the tank or to be decoupled from the tank.

Abstract: A method includes receiving a desired channel indication in a radio tuner, determining a band of operation in which the channel is located, and if the channel is within a first band coupling multiple inductors into a resonant tank, and if the desired channel is within a second band coupling a single inductor into the resonant tank.
