Reconfigurable coil techniques
First Claim
1. An apparatus, comprising:
- a coil, including;
a first electrically conductive portion, a second electrically conductive portion, and a switch coupled between the first and second conductive portions, the switch having a first setting and a second setting;
wherein the first setting provides a first current path, the first current path having a first rotational sense in the first conductive portion and a second rotational sense in the second conductive portion; and
wherein the second setting provides a second current path, the second current path having a same rotational sense in the first and second conductive portions.

Abstract
Techniques are disclosed involving reconfigurable coils. Such coils may be used in applications, including (but not limited to) wireless charging and near field communications (NFC). For instance, a reconfigurable coil may include a first conductive portion and a second conductive portion. Two or more configurations may be established. These configurations may correspond to particular current paths. For example, in a circular configuration, a path is provided having the same rotational sense in both first and second conductive portions. However, in a figure eight configuration, a path is provided having a first rotational sense in the first conductive portion and a second rotational sense in the second conductive portion. A switch coupled between these portions may set the coil'"'"'s configuration. Configurations may be selected based on one or more operating conditions involving the coil.
