Abstract
Systems and methods for runtime antenna matching for wireless power devices are described. The integrated circuit can include a controller. The integrated circuit can further include a circuit configured to sense voltage in a switching converter. The circuit can be further configured to determine whether a negative voltage spike is present or absent in the sensed voltage. The controller can be configured to, based on the presence or the absence of the negative voltage spike in the sensed voltage, tune a capacitance of an antenna interface circuit between the switching converter and an antenna to perform impedance matching.
