E-MOSFET

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....

Enhancement MOSFET Symbol

The Symbol for the N-channel enhancement MOSFET is given below. In the Symbol we can see that the dotted lines which is connected between the Substrate and source terminals shows the enhancement mode type. In the E MOSFET the conductivity is enhances by using increase oxide layer which will add the charge carries in the channel which is known as Inversion layer....

Types of E-MOSFET

Based on the type of charge carriers (electrons or holes), E-MOSFET can be classified into two types:...

N-Channel E-MOSFET

This type of MOSFET is called as n-channel MOSFET because the flow of current takes place by conduction of negative charge carriers, i.e., electrons....

P-Channel E-MOSFET

This type of MOSFET is called as p-channel MOSFET because the flow of current takes place by conduction of positive charge carriers, i.e., holes....

Working of E-MOSFET

The working principle of E-MOSFET is that when a positive voltage is applied on the gate terminal, then a conduction channel appears between source and drain terminal....

Characteristics of E-MOSFET

There are two types of characteristics of E-MOSFET- drain characteristics and transfer characteristics. Both type of E-MOSFET, i.e., n-channel E-MOSFET and p-channel E-MOSFET have these characteristics, and are discussed below:...

Voltage Divider Bias

The Voltage Divider bias for N-channel enhancement MOSFET is given below. This configuration is similar to the divider circuit utilized with BJT transistors.

Conclusion

Thus, E-MOSFET is a type of transistor that consists mainly of three terminals. It is voltage-controlled semiconductor device. In E-MOSFET as no current flows from drain to source when gate is not supplied with any voltage. So, E-MOSFET is generally called as OFF MOSFET as no current flows from gate to source when gate is applied with zero voltage. It could be used both in analog and digital devices as it offers high input impedance with low power consumption....
