應用於 5G 毫米波通訊系統採用差動有預失真線性器和自動適性偏壓技術及轉導補償技術以優化線性度及效率之CMOS功率放大器

Li-Cheng Hung, 洪立誠

本篇論文提出了兩個於 Ka 頻段使用台積電 90-nm 互補式金氧半導體製程 之功率放大器，旨在提升電路的線性度、輸出功率、功率附加效率及退縮 6-dB 處的功率附加效率。 於第一個電路中，我們採用了差動預失真寄生二極體線性器，功率放大器使 用 1.2 V 偏壓供電，級間加入差動預失真寄生二極體線性器以提高電路整體線性 度。由於佈局失誤，於量測時使用第二個電路之相同模態驗證差動預失真寄生二 極體線性器之效能。此三級差動共源極功率放大器在 1.2 V 以及線性器控制電壓 1 V 開啟情況下，實際量測可得 Ka 頻段操作小訊號增益 21 dB、OP1dB 為 16.3 dBm 以及飽和輸出功率 17.5 dBm，於 OP1dB 點的 PAE 與 PAE 的最大值分別為 20.2 %與 23.9 %，而在 P1dB …
