New accurate physics-based closed-form expressions for compact modeling and design of on-chip spiral inductors

摘要

In this paper we present new physically based closed-form inductance expressions for design, compact modeling and characterization of on-chip integrated inductors. We evaluate the accuracy of our expressions, as well as the most popular previously published expressions, by comparing the calculated values with measurement data. It is found that our expressions match the measured inductance values typically within around 5%.
