Abstract
The present document describes a digital power amplifier configured to provide an amplified output signal at an output port based on an input signal. The power amplifier comprises a drive unit configured to generate a high side drive signal comprising a sequence of pulses for controlling the high side switch and a low side drive signal comprising a sequence of pulses for controlling the low side switch, respectively. The drive signals are generated such that the pulses of the high side drive signal are non-overlapping with regards to the pulses of the low side drive signal, and such that the sequence of pulses of the high side drive signal and the sequence of pulses of the low side drive signal have a reduced fraction of energy from higher order harmonics compared to a sequence of rectangular shaped pulses.
