An Efficient Technique for Substrate Coupling Parasitic Extraction with Application to RF/Microwave Spiral Inductors (RESEARCH NOTE)

This paper presents an efficient modeling method, based on the microstrip lines theory, for the coupling between a sub­strate backplane and a device contact. We derive simple closed-form formulas for rapid extraction of substrate parasitics. We use these formulas to model spiral inductors as important substrate-noise sources in mixed-signal systems. The proposed model is verified for the frequencies up to ۳۵ GHz, and is easily adaptable to CAD tools.
