Abstract
An integrated circuit is described. This integrated circuit may include wireless-charger transmitter. The wireless-charger transmitter includes a driver circuit. Moreover, the wireless-charger transmitter selectively filters out an interference signal in a band of frequencies corresponding to AM radio. Note that the selective filtering may be performed by at least a filtering circuit. For example, the filtering circuit may include a low-pass filter. Moreover, the selective filtering using the filtering circuit may be based at least in part on a switching frequency of the wireless-charger transmitter. Furthermore, a filtering frequency associated with the filtering circuit (such as a 3 dB cutoff frequency of a low-pass filter) may be adjusted by selectively electrically coupling a set of capacitors in parallel with the filtering circuit.
