hi all
i put put dual gaurding for my analog circuit.
P plus connect to clean ground.
Nwell guard ring connect to local VDD which i see quite noisy because of the swicthing.
The question is when i put Nwell guard ring which connect to local VDD will make my analog block even noisier? or it will not bring side effect and just not function as guard ring?
tnx for ur feedback.
