Abstract :
This paper investigates substrate noise propagation and attenuation with a focus on analysis for deep submicron structures and short propagation distances. The discussed issues include effects of noise source/target doping types, noise source and target separation distances, presence of guard rings, and the utilization of deep-well structures on noise shielding. Simulation results from 2D simulators MEDICItrade and SEQUOIAtrade are presented in the analysis. We also propose a p-n-p-well with deep n-well guard ring structure which facilitates a fully isolated p-well while providing over 50 dB of noise attenuation up to 10 GHz .
