Features of E-MOSFET
There are various features of E-MOSFET which makes it different from other types of transistors. Some of such features are discussed below:
- In enhancement MOSFET, channel is not present permanently, but it is induced during the time of working.
- A silicon dioxide layer which acts as an insulator is present between gate and substrate which isolates gate from the main structure.
- Due to the presence of metal-oxide (SiO2) layer input capacitance of enhancement MOSFET is high.
- It is a voltage-controlled device.
- E-MOSFET can be operated at very high frequencies (up to few mega-ohms).
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).
