Step five: tune the final stage power transistor quiescent current, the current value of the power tube by measuring the voltage of the emitter resistance Converter and get.
第五步：调末级功率管的静态电流，该电流值可以经由过程测功率管的发射极电阻的电压换算而得到。
We shall take the typical emitter-to-base resistance as about 250 ohms.
我们取发射极基极电阻的典型值为250欧姆左右。
Results show that the resistance relates to the area of the photo-excited region, the side length of the emitter region, the position of the emitter region, and the emitter current.
结果表明该电阻与光敏区面积、发射区边长、发射区位置、发射极电流等因素有关。
This resistance, which is concerned with the doping and shape of the emitter, has a negative feedback action to the emission current of the emitter.
锥体上电位变化可以等效为一个与锥体形状与掺杂相关的串联电阻的作用，这一电阻对单尖发射电流有负反馈作用。
