Assessment of parameter extraction methods for integrated inductor design and model validation

This work analyzes different parameter extraction methods for on-chip integrated inductors and assesses 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 in comparison to the simple nine-element model
