Detailed Solution
Download Solution PDFExplanation:
FET is classified based on the channel in each type.
Based on the channel there are two types:
1) n – channel FET
2) p – channel FET
Based on the formation of the channel
1) JFET
2) Depletion MOSFET
3) Enhancement MOSFET
Field Effect Transistor also has the fourth terminal which is called as “ Body or Substrate”
n – channel JFET
p – Channel JFET
n – channel Depletion MOSFET
p – channel Depletion MOSFET
n – Channel Enhancement MOSFET
p – channel Enhancement MOSFET
NOTE: The difference between Depletion and Enhancement MOSFET is the formation of the channel.
In Depletion MOSFET channel is initially formed whereas in Enhancement MOSFET it is not. So channel in Enhancement MOSFET is represented by the dotted symbol.
