Abstract:

Power amplifier is the most power hungry component of a transmitter. If a conventional power amplifier is used to transmit a high PAPR signal, it will be operating at back-off region where power amplifier has lower efficiency. A CMOS supply modulator architecture is proposed to improve the efficiency of the entire ET PA system.
