Abstract: In an embodiment, an apparatus and system comprising a first inductor with a first diameter; and a switched inductor including a metal layer and a switch; wherein when the switch is closed the switch connects the metal layer of the switched inductor to form an inductor with a parallel circuit enabling current to flow through the switched conductor; and wherein when the switch is open, current is not enabled to flow through the switched conductor. In another embodiment, a method for tuning a high-Q inductor, the method comprising closing a switch of a switched inductor, wherein the switch connects the switched inductor to a first inductor; wherein closing the switch enables current to flow though the switched inductor as well as the first inductor to change the inductance of the high Q inductor.
