英语翻译此电路是电压并联负反馈,输入电阻大,输出电阻小,在电路中作用与分离元件的射极输出器相同,但是电压跟随性能好.

This electric circuit is an electric voltage to merge negative feedback,the importation electric resistance is big,outputting electric resistance small,the function and the separation component shoots the pole exportation machine homology in the electric circuit,but the electric voltage follow behind function good.

Parallel negative feedback circuit voltage, input resistance, output resistance small,Separation of components in the circuit and the role of the emitter output the same, but with good voltage.
