Abstract
A power switched amplifier has a switched output stage which generates an output stage voltage and a filter stage coupled to the switched output stage for smoothing the output stage voltage. The smoothing effect of the filter stage is made to be variable with a control signal. Given little outlay, such an amplifier is capable of generating a well-smoothed output voltage with a high voltage change rate.
