Question
What is the difference between nmos and pmos technologies?
Answers
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.
PMOS are more immune to noice than NMOS.   Your Comment

  • Q We keep a replica of the 'domino directory' (address book) in our local machine along with the mail database. It is for use while outside the office. Recently, i started getting complaints from the users that some addresses are missing from the address book. I checked and found that with every replication (set for both the mail and address book), around 10 to 12 entries were deleted. Currently, i have disabled replication of the address book but that didn't solve the problem. Is there a way to fix this?
