Patent ID: 8531250

Claim:
An integrated circuit incorporating a tunable inductor comprising: a plurality of port terminals comprising at least a first port terminal and a second port terminal; a switch comprising at least a first input and a second input; a first inductance, comprising at least one winding, coupled to the first port terminal and the first input; a second inductance, comprising at least one winding, coupled to at least one of the first port terminal and the first inductance and at least one of the second port terminal and a third inductance; the third inductance, comprising at least one winding, coupled to the second port terminal and the second input; wherein each of the first inductance and the second inductance is substantially disposed on at least one layer within a first bounded horizontal area, and the first inductance is disposed beneath the second inductance; and wherein said switch, when closed, couples said first inductance and said third inductance in parallel with said second inductance.
