This plot is very useful in device characterization because it reflects on the quality of the emitter-base junction while the base-collector bias, $V\_$, is kept at a constant. A number of other device parameters can be garnered either quantitatively or qualitatively directly from the Gummel plot:〔A. S. Zoolfakar et N. A. Shahrol, « Modelling of NPN Bipolar Junction Transistor Characteristics Using Gummel Plot Technique », in 2010 International Conference on Intelligent Systems, Modelling and Simulation (ISMS), 2010, p. 396 ‑400〕 * the common-emitter current gain, $\backslash beta$, and the common-base current gain, $\backslash alpha$ * base and collector ideality factors, $n$ * series resistances and leakage currents. Sometimes the DC current gain, $\backslash beta$, is plotted on the same figure as well. ==See also== *Hermann Gummel *Bipolar junction transistor 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Gummel plot」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
