In a p-type substrate, the n-well can be placed under capacitors, inductors, or bond pads to provide a low-capacitance shield. My question is whether you can leave the n-well terminal floating? In simulation it seems to be ok but not sure if there will be any side effects after fabrication.

Thanks
 

In my opinion, I think it is better to tie the terminal to a clean source to avoid any substrate coupling .
 

So is it ok to connect to a clean ground rather than Vdd? Because I dont have a clean Vdd available.

Thanks
