Deep NWell for a NMOS transistor
Hello all,
I've read in this forum about the purpose of a deep nwell for a NMOS transistor:
one is to isolate NMOS transistors from each other, which is clearly for me.
The other one is to reduce noises, which I can not understand.
I would be thankful if someone could explain me, please:
1. which sort of noises? What is the reason of these noise?
2. how a DNW (deep nwell) reduce noises?
3. Why are DNWs used for NMOS transistors in high-voltage circuits?
