Varying Inductance
First Claim
1. Circuitry comprising:
- a plurality of inductors, each inductor having a first end and a second end; and
a switching arrangement connected to the first end and to the second end of each of the plurality of inductors for routing a current via the inductors;
wherein the switching arrangement is arranged to at least one of;
selectively prevent current from flowing through a subset of the plurality of inductors; and
select a current flow direction through one of the inductors relative to a current flow direction through at least one other of the inductors so as to vary an effective inductance that the plurality of inductors represents to the current.

Abstract
The present application relates to circuitry having a plurality of inductors, each inductor having a first end and a second end; and a switching arrangement connected to the first end and to the second end of each of the plurality of inductors for routing a current via the inductors; wherein the switching arrangement is arranged to at least one of selectably prevent current from flowing through a subset of the plurality of inductors and select a current flow direction through one of the inductors relative to a current flow direction through at least one other of the inductors so as to vary an effective inductance that the plurality of inductors represents to the current.
