Abstract
An integrated circuit for wireless power transfer is disclosed. The integrated circuit may comprise a boost controller configured to pump up a system input to a DC input, an oscillator configured to generate a frequency signal, a MOS (metal-oxide-semiconductor) driver coupled to the oscillator, and a power switch coupled to the MOS driver. The MOS driver may be configured to receive the frequency signal and drive the power switch to convert, based on the frequency signal, the DC input to an AC input to a resonant circuit connected to the integrated circuit.
