Accordingly, two features have become crucial in implementing these integrated systems: wireless communication and efficiency in size and energy consumption. Efforts to facilitate both digital and analog features produce mixed signal System-On-Chip (SOC), which include both analog and digital functions on a single die. Noise coupling in such an environment is a key issue in improving system performance; in particular, the noise coupling through the common substrate (i.e. substrate noise) is unavoidable as physical separation between the functions shrinks with technology scaling. To prevent the system performance from degenerating due to the substrate noise, methodologies for analyzing, estimating and measuring the noise in both simulated and practical conditions are essential and worthy of full investigation. This dissertation has conducted such an investigation in mixed signal SOCs Overall, this dissertation presents methodologies regarding how to understand, estimate, and measure the substrate noise in the mixed-signal SOC. As long as mixed-signal systems prevail in the integrated electronics industry, the SOC as well as the SIP should become the main frames of system implementations, and the presented research can contribute to shaping these frames.
