摘要


本論文以單晶微波積體電路(MMIC)技術設計分別應用於2.4 GHz無線區域網路與3.5 GHz全球互通微波存取系統之高線性功率放大器。本論文中採用的各項電路模型係透過國家晶片中心(CIC)所提供之TSMC 0.18 um CMOS與WIN 0.15 um pHEMT製程所設計。為改善功率放大器在高線性時之效率不足的問題皆採用AB類偏壓設計,並加入線性器維持其線性度。其中針對CMOS疊接架構所造成的相位偏移問題提出補償式電路,改善其電路整體線性度。

In this paper, we designed the high linearity power amplifiers that applying 2.4 GHz WLAN and 3.5 GHz WiMAX systems by monolithic microwave integrated circuit (MMIC) technology. The power amplifiers are implemented with TSMC 0.18 um CMOS and WIN 0.15 pHEMT processes. The power amplifiers employ class-AB topology to overcome the low efficiency when high linearity operated, and using linearizer in the PAs to maintain the high linearity. And we propose a modified circuit to complement the phase deviation of the CMOS cascade topology that could improve the linearity of the power amplifier.
