一般的电路中,有了NPN的,你就可以按“上下对称交换”的方法得到 PNP 的版本。无论何时,只要满足上面的6个“极性”关系(4个电流方向和2个电压不等式),BJT电路就可能正常工作。当然,要保证正常工作,还必须保证这些电压、电流满足一些进一步的定量条件,即所谓“工作点”条件。

Below is the maximum ratings for 2N3904 NPN BJT. As you can see the maximal Emitter-Base voltage is 6 V. I have checked many other BJT datasheets which all show that this voltage is around this value. But in my circuit the Emitter-Base voltage of NPN BJT will be over 6 V which ...

1. Limited frequency response: The transistor has a low cutoff frequency, which limits its use in high-frequency applications. 2. Temperature sensitivity: The transistor’s performance can be affected by changes in temperature, which can impact circuit performance. ...
(BJT), that the base emitter voltage of the dual BJT is about 1.4v is realized in the fixed biascircuit; the comparison and control of the base emitter voltage of the dual BJT and the output reference voltage of the band-gap reference source are realized by the comparator; and thus, ...
