Detailed Solution
Download Solution PDFMOSFET:
The MOSFET is a voltage-controlled field-effect transistor.
It has a “Metal Oxide” Gate electrode which is electrically insulated from the main semiconductor n-channel or p-channel by a very thin layer of insulating material usually silicon dioxide (SiO2), commonly known as glass.
Insulating SiO2 layer provides High input impedance.
MOSFET is of two types:
Depletion type (D-MOSFET):
- Presence of physical layer between source and drain.
- We can apply both positive and negative between source and gate.
Enhancement type (e-MOSFET):
- Absence of physical layer between source and drain
- Only one type of polarity voltage between gate and source such that physical layer should form.
