Classification: CPC H  G | IPC G  H

Claim 0:
1. A device that is operative to transfer power wirelessly, the device comprising:
a drive-sense circuit (DSC) operably coupled to generate a drive signal based on a reference signal, wherein, when enabled, the DSC operably coupled and configured to:
provide the drive signal to a first coil via a single line and via a resonating capacitor and simultaneously to sense the drive signal including to sense one or more electrical characteristics of the drive signal via the single line, wherein the drive signal being provided to the first coil is operative to transfer power wirelessly from the first coil to a second coil of another device; and
generate a digital signal that is representative of the one or more electrical characteristics of the drive signal based on an error signal corresponding to a difference between the drive signal and the reference signal, wherein the reference signal includes a frequency that is based on a resonant frequency associated with an inductance of the first coil and a capacitance of the resonating capacitor.
