US 12,232,264 B1 · High-Q switch inductor

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.

Dependent claims

An apparatus, comprising:

a first inductor comprising at least one tap, wherein the first inductor has a first diameter, and wherein the at least one tap is configured to couple the apparatus to at least one of a transmitter or a receiver;
a switched inductor comprising a metal layer and a switch, wherein the metal layer of the switched inductor has a second diameter, wherein the second diameter is less than the first diameter, wherein, when the switch is closed, the switch connects the metal layer of the switched inductor to form an inductor, enabling current to flow through the switched inductor and the first inductor, and wherein, when the switch is open, current is not enabled to flow through the switched inductor but is enabled to flow through the first inductor;
and
at least two connection points configured to couple the apparatus to a voltage-controlled oscillator.
