Abstract :
A model of a lightly doped substrate is proposed to estimate the substrate coupling noise in the mixed-signal ICs. Compared with previous work, the proposed models both include 3-D substrate network and power/ground network. Developed models of commonly used for isolate noise such as a guard ring and a deep n-well are also proposed. The affectivities of these suppression technologies are compared and quantitatively analyzed to draw a general conclusion.
