    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 …

  2. 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 …

    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。

  3. 现在大部分电路都使用 MOS,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 …

  4. BJT与MOSFET的开关速度谁更快?高频特性谁更好? - 知乎

    BJT的载流子(电子和空穴)在体内运动,迁移速度快,而MOSFET作为表面器件,载流子(多数载流子)在表面沟道中运动,迁移速度相对较慢。 "BJT的Base很窄,重掺杂的emiiter的多子 …
