Zusammenfassung:In this paper, a novel approach to parameter extraction for on-chip transformers based on four-port Y-parameter is presented. Compared to the previous researches, the proposed fully parameter extraction from Y-parameter has better accuracy and feasibility for both the simulation before prototype and the improvement of the design after the measurement. And the 4-port model of transformer provides the solution of the fully differential applications. The model agrees very well with measurements for a variety of transformer configuration up to its self-resonant frequency.
