Mixed-signal IC design guide to enhance substrate noise immunity in bulk silicon technology
Predicting substrate cross-talks in mixed-signal circuits has become a critical issue to preserve signal integrity in future integrated systems. Phenomena that involve substrate parasitic voltage and substrate propagation are discussed. A simple methodology to predict the substrate cross-talk and some associated tools are presented. A typical study shows the possibility of such a method and measurements finally demonstrate its efficiency.
