Resolving differences of parameter extraction methods for integrated inductor design and model validation

Abstract

This work analyses different parameter extraction methods for on-chip integrated inductors and their impact on inductor design. The relationship between extracted single-ended and differential parameters is investigated through the use of theoretical network models that support the calculation equations. Experimental results from a test chip are presented and a lumped model, which adequately simulates the inductor performance with and without ground shield, is validated.
