Low-cost EM-driven surrogate modeling and optimization of planar inductors

This work presents an accurate surrogate model of a planar inductor realized in a 65-nm CMOS technology. The main components of our modeling approach include coarse-discretization electromagnetic simulations, kriging interpolation, and space mapping. The surrogate model constructed this way is accurate over a broad frequency range and, as showcased by our examples, can be used to perform reliable and rapid design optimization of an integrated inductor.
