dc.description.abstractThis paper presents the `Envelope Following’ Technique for raising power efficiency in mobile communication systems. The designed power supply system includes a 2.13 GHz power amplifier in which the input battery voltage of 5 V is boosted to a variable voltage output of 28 V depending on the incoming radiofrequency envelope. This variable voltage is obtained using an envelope detector and a dc-dc boost converter. For an output power level of 45 dBm, the power efficiency increases from 72.4% to 85.4% extending battery life over 1.2 times.es_ES
