Classification of MOSFETs


Depending upon the type of materials used in the construction, and the type of operation, the MOSFETs are classified as in the following figure.

Description: MOSFET Classification

After the classification, let us go through the symbols of MOSFET.

The N-channel MOSFETs are simply called as NMOS. The symbols for N-channel MOSFET are as given below.

Description: N-Channel MOSFET

The P-channel MOSFETs are simply called as PMOS. The symbols for P-channel MOSFET are as given below.

Description: P-channel MOSFET

Now, let us go through the constructional details of an N-channel MOSFET. Usually an NChannel MOSFET is considered for explanation as this one is mostly used. Also, there is no need to mention that the study of one type explains the other too.
