Zusammenfassung:	A system and method for configuring a tunable inductor that minimizes Q factor are provided. The system and method comprise coupling a first inductance, a second inductance, a third inductance, a switch, and two port terminals. The first inductance and the third inductance are coupled between the switch and the port terminals. The second inductance is coupled between the port terminals or between the first and third inductance. The inductances are each disposed on at least one layer, wherein the first inductance is disposed beneath the second inductance and the third inductance is disposed on the same layer as the second inductance. The components are arranged such that toggling the switch tunes the inductance without adversely affecting the Q factor.
