Efficient Modeling of Distributed Electromagnetic Coupling in RF/Microwave Integrated Circuits

Abstract:- Because of ever-higher operating frequencies and circuit integration, distributed electromagnetic (EM) coupling effects are becoming increasingly important in RF/microwave integrated circuits. Although existing EM-based models for passives are accurate, they do not adequately include distributed EM coupling between adjacent components. In this paper, the authors introduce the concept of automatic generation of accurate and fast neural models for passives that can efficiently integrate distributed EM coupling effects between adjacent elements. Examples of passive device modeling and use of these models in commercial circuit simulators demonstrate that the proposed approach is a generic method which can allow to extend the present capabilities to a large variety of RF/microwave circuit design and optimization
