A CMOS RF Polar Transmitter of a UHF Mobile RFID Reader for High Power Efficiency

A CMOS radio frequency (RF) polar transmitter architecture for a UHF (860-960 MHz) RF identification (RFID) reader is proposed, which consists of a switch-mode CMOS power amplifier (PA) and an analog pulse-shaping filter implemented in 0.25-mum CMOS process. The amplitude modulation of a amplitude s...
