Which one of the following is not a basic MOSFET device type?a)Enhance...
Introduction:
MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of field-effect transistor widely used in electronic devices. It is an essential component in integrated circuits and is available in various types, each with its own characteristics and applications.
Explanation:
Among the given options, the correct answer is option 'C', which states that a "Narrow P-channel MOSFET" is not a basic MOSFET device type. Let's understand why this is the case:
1. Enhancement MOSFET:
- An enhancement MOSFET is the most common type of MOSFET.
- It requires a gate-source voltage to create a conducting channel between the source and drain terminals.
- It operates in both N-channel and P-channel configurations.
- In an enhancement P-channel MOSFET, a positive gate-source voltage is applied to turn it on.
- In an enhancement N-channel MOSFET, a negative gate-source voltage is applied to turn it on.
2. Depletion MOSFET:
- A depletion MOSFET is less commonly used compared to an enhancement MOSFET.
- It has a conducting channel between the source and drain terminals even with zero gate-source voltage.
- It operates in both N-channel and P-channel configurations.
- In a depletion P-channel MOSFET, the gate-source voltage is zero to turn it on.
- In a depletion N-channel MOSFET, the gate-source voltage is negative to turn it on.
3. Narrow MOSFET:
- The term "Narrow" does not refer to a specific MOSFET type but rather describes a particular characteristic of a MOSFET.
- It indicates that the channel width of the MOSFET is small compared to its length.
- Narrow MOSFETs are often used for high-speed switching applications or in areas where space is limited.
- Therefore, "Narrow P-channel MOSFET" is an incorrect term as it does not specify a basic MOSFET type.
Conclusion:
In conclusion, the given options include three basic MOSFET types, namely enhancement P-channel MOSFET, depletion N-channel MOSFET, and enhancement N-channel MOSFET. However, "Narrow P-channel MOSFET" is not a basic MOSFET type but rather describes a characteristic of a MOSFET.

Which one of the following is not a basic MOSFET device type?a)Enhance...
MOSFET:
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.
Symbol representation of MOSFET:
