Combination of Metaheuristics to the Optimal Design of Analog and RF Circuits

Abstract

Multi-objective metaheuristics are over and over again used by analog designers. They allow generating a set of non-dominated solutions (i.e. the Pareto front). In this chapter, the authors highlight the fact, via the application of six multi-objective algorithms to the optimization of conflicting performances of four analog and RF circuits, that the generated fronts highly depend on the used algorithm. They propose a solution consisting of combining metaheuristics to generate a “better” front by merging results obtained thanks to different algorithms and the application of a dominance routine. Viability of the proposed idea is shown through examples.
