Accelerated multi-objective design of integrated spiral inductors using Pareto front extrapolation

In this work, we demonstrate accelerated multi-objective optimization of integrated inductors by means of Pareto front exploration. The objectives of interest include minimization of the component area, maximization of the quality factor, as well as maintaining required inductance value at a given operating frequency. A set of Pareto-optimal designs is found by moving along the Pareto front using local optimization methods. Considerable reduction of the design cost is achieved by extrapolating inductor dimensions at the subsequent optimal point based on already available data. An illustration example is provided.
