Abstract
An apparatus comprising two inductors; wherein the two inductors are layered on top of each other in different layers of metal of a circuit; wherein each inductor of the inductor has a set of turns; wherein the current path of the two inductors is in the same direction.
Claims16
An apparatus comprising:
- two inductors;
- wherein the two inductors are layered on top of each other in adjoining layers of metal of a circuit spaced to cause the field of the inductors to couple;
- wherein each inductor of the two inductors has an equal set of turns;
- wherein the current path of the two inductors is in the same direction, wherein the two inductors have the same inductance;
- wherein the two inductors are connected in parallel;
- and a set of switches, wherein each switch of the set of switches is connected to a different turn of the set of turns of a first inductor of the two inductors and to a corresponding turn of the set of turns of a second inductor of the two inductors to create a variable inductor, and wherein an inductance of the variable inductor is to change based on a switch of the set of switches being shorted.

A system comprising:
- a first inductor;
- a second inductor;
- wherein the first and second inductors are layered on top of each other in adjoining layers of metal of a circuit spaced to cause the field of the inductors to couple;
- wherein the first inductor has a set of turns;
- wherein the second inductor has an equivalent set of turns;
- wherein the current path of the two inductors is in the same direction, wherein the two inductors have the same inductance;
- wherein the two inductors are connected in parallel;
- and
- a set of switches, wherein each switch of the set of switches is connected to a different turn of the set of turns of the first inductor and to a corresponding turn of the set of turns of the second inductor to create a variable inductor, wherein an inductance of the variable inductor is determined based on shorting a switch of the set of switches.
