Hi,
I'm trying to shield the mimcap from the substrate. This is for my ADC design.
I have two-options. first is to put NWell beneath the cap. the other one is to put deep nwell beneath it.
Obviously, deep-nwell is better. But is it really necessary to shield it with a deep-nwell?
What is the common practice for mimcaps?
