Digitally controlled envelope tracking power supply for an RF power amplifier

A new digital self-oscillating (DiSOM) modulator is presented in this paper. The advantage of the DiSOM is that it allows the sampling frequency of the digital compensator to be higher than the switching frequency, but it also has the ability to shape the quantization noise on the switching output d...
