  1. 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 …

  2. BJT三极管,原理实质上真的是电流控制器件吗?总感觉其实是电压控 …

    图1 三极管电路与等效模型 由暗示变为明示:发射极电流Ie由基极电流Ib控制;一个小电流控制着一个大电流,还自带些许四两拨千斤的磅礴气势。 更进一步,有不少文章、甚至教材直接写到: BJT三极 …

  3. 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 …

  4. How do you turn on an NPN BJT Transistor? - All About Circuits

    Oct 8, 2016 · So.. here it goes. I'm going to try give my hypothesis, as to how these NPN BJT Transistors work. The Vebo (Emitter Base Voltage) is the positive voltage to be applied to the Base, …

  5. 晶体三极管如何工作的?我是问它的真实工作原理? - 知乎

    晶体管(BJT)的本质是至少需要0.7V才能将其打开,通过基极的电流是性能的决定性因素。 随着基极电流增加,集电极电流也增加。 晶体管(BJT)和MOSFET不同,MOSFET是在栅极电压上的作用比 …

  6. BJT transistor storage time - All About Circuits

    Jun 26, 2015 · What does "storage time" in a bjt transistor mean? For example, in the 2N3906 datasheet it says: I understand delay, rise and fall times... but is storage time the "delay time" that it takes for …

  7. Base to Ground resistor in BJT application - All About Circuits

    Aug 19, 2010 · Hi, I'd like to ask a couple of questions please regarding the below circuit. 1. What is the role of Rbe? What is it needed for? 2. Is Rbe connected to Ground (on its bottom side) because the …

  8. 三极管和 MOS 管的区别是什么? - 知乎

    三极管(BJT:双极型晶体管)和MOS管(MOSFET:金属-氧化物-半导体场效应晶体管) 都是可控开关。三极管(BJT)通过对Ibe电流来实现对Ice大小的控制,MOSFET通过对Vgs电压实现对Rds电 …

  9. How does a diode-connected BJT work? | All About Circuits

    Jun 21, 2018 · A BJT is best thought of, in most circumstances, as a voltage-controlled device in the active region. The collector current is controlled by the base-emitter voltage.
