Abstract
A power switching amplifier for digital power amplification of an analog input signal, wherein the input signal range is subdivided into a plurality of equal voltage steps and a number, corresponding to the number of voltage steps, of switching stages is driven and their direct-voltage sources are connected in series. The association between the voltage steps and the switching stages is variable, such that all switching stages are uniformly loaded and the switching frequencies are reduced.
