Abstract

In an embodiment, a wireless power transmitter is disclosed that includes a first field-effect transistor, a second field-effect transistor a coil and an analog front end. The wireless power transmitter is configured to drive the coil based at least in part on activations of the first and second field-effect transistors. The analog front end includes a first driver corresponding to the first field-effect transistor and being configured to control activation of the first field-effect transistor based at least in part on a pulse-width modulation signal and a second driver corresponding to the second field-effect transistor and being configured to control activation of the second field-effect transistor based at least in part on the pulse-width modulation signal.
