Abstract
An analysis procedure is presented allowing the systematic optimisation of buck-converters, which are required for the efficiency enhancement of power amplifiers in back off mode. All relevant parasitics are included. Based on this model the performance of the envelope following and tracking approaches are investigated for common communication standards such as GSM, UMTS and WLAN. Efficiency enhancements of above 100% are shown.
