Exemplary embodiments are directed to differentially driving a load. An apparatus includes a differential drive amplifier including a switching device coupled with a first output node and a second output node. The first output node and the second output node drive a load network including primary coils. The differential drive amplifier also includes a drive circuit configured to drive the switching device. The drive circuit may be configured to provide a drive signal to the switching device to alter a conductive state of the switching device to produce a first output signal at the first output node and a second output signal at the second output node. The first and second output signals may be substantially equal in magnitude but opposite in polarity relative to a reference voltage.
