dc.description.abstract | A dynamic feedback linearizer for an RF CMOS power amplifier (PA) is presented, which consists of a negative feedback network and a dynamic feedback control circuit to inject a reshaped envelope signal to the network. The linearizer compensates for the gain compression of the RF CMOS PA in high-power region by reducing the feedback dynamically, and it also reduces the amplitude-to-phase modulation (AM-PM) distortions. The PA including the linearizer was fabricated using a 0.18-mu m RF CMOS process, which has an output transmission-line transformer on a printed circuit hoard. It delivers an output power of 28.1 dBm at 1.7 GHz with power added efficiency of 40.9%, and adjacent channel leakage ratio (ACLR(E-UTRA)) of under -30 dBc for a 10-MHz 16-QAM long-term evolution signal without digital predistortions. | - |
