A linear power amplifier (PA) is used for powering high-bandwidth modulated signals with high peak-to-average power ratio (PAPR). The efficiency of a PA significantly degrades using a fixed supply voltage, and an envelope-tracking (ET) power supply remains an essential alternative for improving the energy efficiency. This paper shows that a single-inductor… CONTINUE READING
