To improve the power efficiency of the conventional linear PA [1-4], an envelope tracking (ET) technique, which modulates supply voltage of a linear PA, has attracted attention. However, the published power efficiency, gain and output power are not sufficient for LTE applications [5], and its typical implementation requires an external supply modulator that is a high-speed power supply circuit [6]. Envelope elimination and restoration (EER) is an alternative supply modulation technique that can further
