Abstract
In described examples, an inductive structure includes a power coil and a data coil. The data coil is substantially centered within the power coil. A first portion of the data coil is for conducting current in a first direction. A second portion of the data coil is for conducting current in a second direction opposite the first direction. The first portion of the data coil is connected at a ground node to the second portion of the data coil. The power coil is for: receiving power without data; and outputting the received power without data.
