Abstract :
In this paper, the most relevant characteristics of the substrate noise spectrum for mixed-signal integrated circuits (ICs) are derived using a simple analytical model. These characteristics are related to parameters of the digital circuit, the package + printed circuit board parasitics, and other elements of the mixed-signal IC. The model used to derive the substrate noise spectral characteristics includes the statistical properties of the digital switching current waveform and the coupling transfer function between the digital power supply nodes and the substrate node of the victim circuitry. The results of the work are validated experimentally on a mixed-signal prototype
