有射极电阻的基本电路中双极型晶体三极管工作状态的一种判断方法

摘要

This paper presents a method for judging the working state of bipolar transistor in the basic circuit containing emitter resistances.In the basic circuit containing emitter resistances,if the resistance value in the circuit,BJT current amplification factorβand DC power supply voltage value are the only given conditions,we can assume that BJT is in the state of amplifying and figure out the col ector current IC or the base current IB of this state,then compare these values respectively with the col ector current ICS or the base current IBS in the critical saturation state:If IC
