Step five: tune the final stage power transistor quiescent current, the current value of the power tube by measuring the voltage of the emitterresistance 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.
