WebApr 12, 2012 · The BJT is formed by two p-n junction (either npn or pnp ), so at a first glance it's symmetrical. But both the concentration of dopant and the size of the regions (and more important: the area of the junctions) is different for the three regions. So it simply won't work at the full potential. (like using a reversed lever) Web1. BJT: structure and basic operation Bipolar Junction Transistor: excellent for analog and front-end communications applications. n+ n+ n+ n+ n+ polysilicon contact metal contact …
WebBJT operation modes The transistor can be operated in three modes: Cut-off mode Saturation mode Active mode In order to operate transistor in one of these regions, we have to supply dc voltage to the npn or pnp transistor. Based on the polarity of the applied dc voltage , the transistor operates in any one of these regions. WebActive, saturation, & cutoff state of NPN transistor Google Classroom About Transcript Let's explore the three different behaviours the transistor exhibits.

WebDec 27, 2010 · BJT is called Bipolar instead of a Unipolar like MOSFET or JFET. As you can see, both holes and electrons are active carriers. Electrons and Holes are opposite poles (i.e. having opposite polarities), thus calling any transistor with such distinction a Bipolar Junction Transistor.
