A review of substrate coupling issues and modeling strategies

This tutorial paper reviews the technologies behind substrate coupling and modeling. The key focuses throughout are the importance of suitable substrate models and a sufficient understanding of the substrate coupling in the circuit being designed. Discussions include Radio Frequency (RF) and Mixed-Signal (MS) designs, but also touch upon System-on-Chip (SoC). An example RF circuit is simulated with a substrate model and the effect of substrate process variations on the circuit's performance is discussed.
