A fast modulator for a dynamic supply linear RF amplifier has been integrated in a 0.35-μm CMOS technology. The use of this modulator with an external linear power amplifier (PA) allows to maintain its efficiency at a higher level than it would with the same PA supplied at constant voltage. The modulator is designed to follow rapid envelope variations at high efficiency without compromising the RF PA linearity.
