The continuous and rapidly growing demand for mobile communication access led to a major increase in the number of base stations worldwide to provide sufficient coverage and quality of service. As a consequence, mobile communication networks have become a significant contributor to global energy consumption. Several advanced topologies for efficiency improvement of RF power amplifiers have been developed. Modulating the amplifier¿s supply voltage according to the variation of the envelope signal is one of the most promising concepts. This topology is investigated here, with an architecture that switches the supply voltage of the power amplifier in discrete levels with a class-G supply modulator. The thesis addresses
