An impedance modulated class-E polar amplifier in 90 nm CMOS

This paper presents a digital amplitude modulator for a polar transmitter. The instantaneous output power is modulated by adjusting the amplifier's load through a digitally controlled impedance transformation network. The modulator is suited for modulation schemes with moderate peak-to-average...
