What Is The Difference Between Nmos And Pmos Technologies?
Answer»
PMOS consists of metal oxide semiconductor that is made on the n-type substrates and consists of active careers named as holes. These holes are used for migration purpose of the CHARGES between the p-type and the drain. Whereas, NMOS consists of the metal oxide semiconductor and they are made on p-type substrates. It consists of electrons as their carriers and migration happens between the n-type source and drain.
On applying the HIGH voltage on the logic gates NMOS will be conducted and will get activated, whereas PMOS require low voltage to be activated.
NMOS are faster than PMOS as the carriers that NMOS USES are electrons that TRAVELS faster than holes. The SPEED is twice as fast as holes.
