在射极偏置放大器中PNP型晶体三极管工作状态的确定

Determination of Active Status of PNP Semiconductor Triode in Emitter-Biased Amplifier

根据PNP型晶体三极管的工作原理,借助等效电源电压和射极偏置放大器中晶体三极管静态工作点电压、基射极导通电压之间大小关系,研究了确定射极偏置放大器中PNP型晶体三极管工作状态的方法,提出了一种简易可行的判据.

According to the principle of PNP semiconductor triode, the method to determine the active status of the PNP triode in Emitter-Biased Amplifier can be investigated by using quantitative relations of equivalent supply voltage, quiescent voltage and the break-over voltage of Base-Emitter of the trioder. A simple and feasible determination criterion of the active status are provided in the article.
