NMOS Vs PMOS
MOSFETs are classified into two types called NMOS and PMS. The basic difference between NMOS and PMOS is that the source and drain terminal in NMOS is made of n-type semiconductors, while the source-drain terminal in PMOS is made of p-type semiconductors. This article on NMOS Vs PMOS MOSFET describes the basic difference between NMOS and PMOS types of MOSFET.
What is NMOS?
An NMOS is a kind of MOSFET. An NMOS transistor is made up of an n-type source and drains as well as a p-type of subtracting. When a voltage is applied to the gate, it causes holes in the body to move away from the gate. This allows an n-type channel to form between the source and the drain, and electrons are conducted from the source to the drain via an induced n-type channel.
What is PMOS?
A PMOS is a kind of MOSFET. The source and drain in PMOS devices are made of p-type material, while the bulk is made of n-type semiconductors. Electrons are repelled when a negative voltage is applied to the gate, allowing holes to form a channel and travel between the source and the drain. The majority of carriers in PMOS are holes because holes move much slower than electrons, it is much easier to control the current.
