To reduce noise coupling it is said to put resistors and capacitors in nwell in layout.
What is nwell tied too ? Is nwell also surrounded by nwell guard ring? So what is nwell guard ring connected to ? It should be quiet - so analog ground ?
The application is for a SAR ADC's capacitive DAC.
If cap and res are three terminal devices in kit - what is third terminal connected to if placing them in nwell ?
