IEEE 802.11b/g High Efficiency CMOS Power Amplifier with an Integrated Adaptive Bias Circuit
本論文探討以UMC CMOS 0.18um RF製程來實現Doherty PA電路架構,以提高6dB-backoff 時的功率輸出效率。經由S參數的量測,在2.4GHz的頻段中,有10.6dB的小訊號增益。該電路的最大輸出功率與P1dB分別為22.6dB與21.4dBm。此時PAE最高可達33.6%,於P1dB點為32.6%,在6dB-backoff時仍高達21.1%的高效率值。由於晶片內部不需採用螺旋電感,其晶片面積僅666*999 µm2。The Doherty power ...
