difference between n-channel FET vs p-channel FET

This page on n-channel FET vs p-channel FET mentions difference between n-channel FET and p-channel FET. Ocr for mac free download.

Following section compares both FET types with respect to their features, symbol and construction.

n-channel FET

As shown in figure-1, n-channel FET is constructed using a bar of N-type material into which a pair ofP-type regions are diffused. Fig-1 also mentions circuit symbol of n-channel FET.

Following are the features of N-channel Junction FET(JFET):
• Current carriers are electrons in n-channel FET.
• Mobility of electrons is large.
• Input noise is low.
• Trans-conductance is large.

p-channel FET

Similar to n-channel FET, p-channel FET is constucted using a bar of P-type material into which a pair ofN-type regions are diffused. Fig-2 mentions circuit symbol of p-channel FET.

Following are the features of P-channel Junction FET(JFET):
• Current carriers are holes in p-channel FET.
• Mobility of holes is poor.
• Input noise is large.
• Trans-conductance is small.

From the comparison between n-channel FET and p-channel FET it isimperative that n-channel FET serves better than p-channel FET.
