Abstract
In accordance with an embodiment, a method includes driving at least one electronic switch coupled to at least one inductor in a converter stage of a switched mode power supply based on a clock signal, and modulating a clock frequency of the clock signal over a predefined first frequency range around a center frequency such that a frequency spectrum of the clock signal is asymmetric. The switched mode power supply includes a filter coupled between the converter stage and an input of the switched mode power supply.
