What is Enhancement Type MOSFET?
The full form of E-MOSFET is Enhancement- Metal Oxide Semiconductor Field Effect Transistor. It is called as enhancement MOSFET because for a creating a conduction channel between drain and source terminal, a positive voltage is required at the gate terminal. Metal is for the metallic contacts that are used to connect drain(D), gate(G) and source(S) terminals.
Oxide is for the silicon dioxide (SiO2) layer which is used as an insulating layer between substrate and gate terminal. Semiconductor is for the structure which is used in the construction of this transistor. To sum up, the name E-MOSFET is given to this type of device.
E-MOSFET
Enhancement MOSFET which is commonly called as E-MOSFET is a type of field effect transistor which is used mainly in voltage-controlled devices. It is a unipolar device, i.e. device in which conduction of current takes place either by electrons or holes. It is a three-terminal device which is mainly used as amplifier or in switching devices.
This type of transistor can be used both in analog and digital devices. These transistors are more popular than Bipolar junction transistors due to less power dissipation and negligible leakage current. These are smaller in size and hence find its application in integrated circuits (ICs).
