Description
本願は2019年4月24日に出願された米国特許出願第16/393,280号の優先権を主張し、その内容の全体を参照により本明細書に組み込む。
によって与えられ、上式で、Rorig及びWorigは、それぞれ元のゲート・フィンガ構成(例えば図2Aのゲート・フィンガ210)のゲート抵抗及びゲート・フィンガ幅であり、Wnewは新しい構成のゲート・フィンガ(例えば図5Aのゲート・フィンガ510)の幅である。式1から分かるように、ゲート・フィンガ幅をWから2Wへと大きくすると、ゲート抵抗は2倍になる。ゲート抵抗を大きくする結果、増幅器の重要な仕様であるトランジスタ利得が、より低くなる可能性がある。例えば、ゲート・フィンガ長さWを有するトランジスタが出力電力Pを生成する場合、ゲート・フィンガ510の幅を2倍の2Wにすることで、生成される出力電力は2Pよりも小さくなる。この非線形であるスケーリングはまた、電力増幅器の設計者が所与の出力電力要件に合わせて適正なトランジスタ・ダイのサイズを選択するのを困難にする。抵抗が増加すると増幅器の効率も低下する。
