Abstract :
This brief investigates the substrate noise coupling using S-parameters measurement. Radio frequency domain analysis shows that the noise isolation is strongly dependent on layout geometry, including the parameters such as p-n junction, physical separation distance, guard ring (GR), and deep n-well (DNW). We found that the noise coupling can be efficiently diminished by incorporating GR and DNW structures.
