    摘要: 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.
