A variable integrated inductor is described herein which has an inductance value that can be switched between two or more values. In the preferred embodiment, the variable integrated inductor includes a multi-loop primary inductor which is electromagnetically coupled to a pair of secondary inductors. The secondary inductors are connected to one another to form a closed circuit within which the secondary inductors have a changeable topology that can be switched between a series connection and a parallel connection in order to change an inductance value which is output by the multi-loop primary inductor. In one application, the variable integrated inductor is used in a voltage controlled oscillator (VCO) which is of the type that can be used in a multi-band RF radio transceiver (e.g., wireless communication device). In other applications, the variable integrated inductor can be used in a tuned amplifier load, an impedance matching network, a digitally controlled oscillator or any other type of frequency selective LC-network.
