What is pfet?

A pFET (p-channel field-effect transistor) is a type of MOSFET (metal-oxide-semiconductor field-effect transistor) that uses a p-type semiconductor as the channel. When a positive voltage is applied to the gate of a pFET, it creates an electric field that repels the holes (positive charge carriers) in the p-type material, allowing current to flow from the source to the drain.

pFETs are commonly used in digital and analog circuits to control the flow of current. They are often used in CMOS (complementary metal-oxide-semiconductor) technology along with nFETs (n-channel field-effect transistors) to create logic gates and other electronic components.

pFETs have a lower electron mobility compared to nFETs, which can affect their performance and speed in certain applications. However, pFETs are still essential components in many electronic devices and circuits.
