Study and analysis of wounded integrated L-C passive components

The aim of the paper is to present simple and effective methods to study and to analyse wounded integrated L-C components using finite element analysis considering coupled electro-magnetic and electro-static modelling and discrete models. Once the FEA modelling technique is presented, it is applied to simple winding structures creating a series L-C function. Simulation results are provided and validated with respect to experiments. Then, analysis is performed to understand the behaviour of the component with respect to coupled phenomena. Empirical L-C circuit design formula are validated. A new discrete model is derived from this analysis. It is validated on a regular L-C integrated circuit design. Measurements of the different L-C functions using impedance analyser characterisation are provided.
