BJT、JFET、MOS管，最基础的3种三极管。在原理上，他们的共性是什 …
BJT的关键变量是Vbe、Vce、Ic，JFET与MOS管的关键变量都是Vgs、Vds、Id。 由这些具体可以概括出： 三极管需要处理的变量都是3个，即控制量、主通道电压、主通道电流。 做数据拟合的时候，3个变 …
BJT三极管，原理实质上真的是电流控制器件吗？总感觉其实是电压控 …
都2022年了，「BJT三极管是电流控制器件」的观点，还在流行。 不仅掩盖了三极管有趣的灵魂，还遮蔽了半导体中磅礴的力量。
现在大部分电路都使用 MOSFET，为什么还要学 BJT？ - 知乎
BJT作为输出级时，只要将BJT接成射极跟随器（共集电极组态），单管就很容易做到100欧姆以下的输出电阻，如果是大电流功率输出级，由于电导调制效应的作用，发射结电阻极低，很容易做到几个欧姆 …
