摘要
修正了电流增益表达式。对样品3DK105B在不同温度点下进行测试分析。考虑样品理想因子n随温度的变化、VBE随温度的变化,以及禁带宽度随温度变化对电流增益的影响,对电流增益表达式进行了修正,使修正后的结果更加接近实际测试结果。
Expression of current gain was corrected.Sample 3DK105B was tested and analyzed at different temperatures.Taking effects of variations of ideal factor nof the sample,base-emitter voltage VBEand bandgap with temperature on current gain into consideration,expression of current gain was corrected,which made theoretical calculation closer to results from actual test.
