Abstract :
A digital driver enabling the use of highly efficient, switched DC-DC converters for dynamic supply of radio frequency (RF) power amplifiers (PA) is proposed in this paper. Its design procedure, targeting a FPGA implementation, is fully detailed. Using simulation procedures, the potential of the proposed driver to enhance both PA linearity and efficiency figures in wideband RF applications is highlighted, as well as its robustness in front of temporal misalignments between the RF and the supply paths.
