dc.description.abstract | A CMOS saturated power amplifier (PA) is developed for optimally implementing the envelope-tracking (ET) transmitter. The CMOS saturated PA is used to maximize the efficiency of the ET PA. The dynamic feedback control and the biasing techniques at the gates of the common-gate stage and the common-source of the cascode structure are proposed to improve the dynamic range, linearity and efficiency. The fully-integrated CMOS PA with a supply modulator is fabricated using a 0.18-mu m RF CMOS technology. For a long-term evolution signal at 1.85 GHz with a 10-MHz bandwidth and a 16-quadrature amplitude modulation 7.5 dB peak-to-average power ratio, the ET-based CMOS PA module delivers a power-added efficiency of 37.6%, an error vector magnitude of 2.4%, and an an evolved universal terrestrial radio access adjacent channel leakage ratio (ACLR(E-UTRA)) of -36.8 dBc at an average output power of 26.5 dBm. The proposed auxiliary circuits enable the ET-based CMOS PA to provide the significantly improved performance. | - |
