A new design methodology for radiofrequency circuits is presented that includes electromagnetic (EM) simulation of the inductors into the optimization flow. This is achieved by previously generating the Pareto-optimal front (POF) of the inductors using EM simulation. Inductors are selected from the Pareto front and their S-parameter matrix is included in(More)
This work is aimed to compare the performance of toroidal inductors and planar spiral inductors in multi-layered technologies. Toroidal inductors are investigated theoretically, and closed formula is derived for the inductance as a function of geometrical parameters. The obtained model is validated by experimental results and EM simulation. From the(More)
In this paper, a new methodology for the automated generation of the optimal performance trade-offs of integrated inductors is presented. The methodology combines a multiobjective optimization algorithm with electromagnetic simulation to get highly accurate results. A set of sized inductors is obtained showing the best performance trade-offs for a given(More)
