WHAT ARE THE TYPES OF TRANSISTOR?

TYPES OF TRANSISTOR:

There are two main types of transistor..
1)BJT(Bipolar Junction Transistor)
2)MOSFET(Metal Oxide semiconductor Field Effect Transistor)

BJT:

--->npn or pnp silicon structure
􀂃--->Small current into very thin base layer controls large currents between emitter and collector

--->􀂃 Base currents limit integration density


MOSFET:
--->nMOS and pMOS MOSFETS
---> Voltage applied to insulated gate controls current between source and drain
---> Low power allows very high integration
