Gate materialThe primary criterion for the gate material is that it is a good conductor. Highly doped polycrystalline silicon is . See moreAs the channel length, L, is reduced while the supply voltage is not, the tangential electric field will increase, and the carrier velocity may saturate. εc ≈ 104 V/cm for electrons. Hence for N-channel MOSFET with L < 1 µm, velocity saturation causes the channel current to reach saturation before VD = VG - VT.

An P-Channel MOSFET is made up of a P channel, which is a channel composed of a majority of hole current carriers. The gate terminals are made up of N-type material. Depending on the voltage quantity and type (negative or positive) determines how the transistor operates and whether it turns on or off.

Δψ is the difference in the surface potential between the drain and the source. Q inv0 and Q invL are the inversion charge densities at the source and drain, respectively. Q ¯ i n v is the average inversion charge density across the channel.
A MOSFET is a three-terminal device in which the gate terminal is insulated from the channel by a silicon dioxide (SiO2) layer, therefore, it is also known as an insulated gate field effect transistor (IGFET), MOSFET works like a MOS capacitor which is controlled by the input gate to source voltage.

A N-Channel MOSFET is a type of MOSFET in which the channel of the MOSFET is composed of a majority of electrons as current carriers. When the MOSFET is activated and is on, the majority of the current flowing are electrons moving through the channel. P-Channel Enhancement MOSFET: Uses a lightly doped n-type substrate and forms a conductive channel when a negative gate voltage is applied, allowing current flow. N-Channel Enhancement MOSFET: Utilizes a lightly doped p-type substrate and forms a conductive channel with a positive gate voltage, enabling current flow.

That's why MOSFET can also be used as a voltage-controlled capacitor. In this article, we will discuss what is N channel MOSFET, its types and classification, testing, Applications, advantages and disadvantages, FAQs, Conclusion, etc. In this article, we will learn the Basics of MOSFET, its internal construction, how it works, and how to use them in your circuit designs. If you want to skip the theory, you can check out the article on popular MOSFETs and where to use them to speed your part selection and design process. In this section, we will explore the structure and operation of MOS transistors, discuss the differences between N-Channel MOS (NMOS) and P-Channel MOS (PMOS) transistors, and examine the key characteristics that define their performance in electronic circuits.MOS Transistor CHAPTER OBJECTIVES This chapter provides a comprehensive introduction to the modern MOSFETs in their on state. (The off state theory is the subject of the next chapter.) It covers the topics of surface mobility, body effect, a simple IV theory, and a more complete theory applicable to both long- and short-channel MOSFETs.
