abstract = "A high efficiency wideband envelope tracking power amplifier with low quiescent power is presented. The CMOS envelope amplifier has a combined linear amplifier and switching amplifier to achieve high efficiency and wider bandwidth. Quiescent power of the envelope amplifier is reduced using a source cross-coupled linear amplifier with inherently low DC power dissipation. Measurements show a power added efficiency of 45% for the envelope tracking power amplifier for 20 MHz LTE signal with 6.0 dB PAPR at 2.5 GHz at 1W output power.",
