Computational intelligence techniques for determining optimal performance trade-offs for RF inductors

Abstract

The automatic synthesis of integrated inductors for radio frequency (RF) integrated circuits is one of the most challenging problems that RF designers have to face. In this chapter, computational intelligence techniques are applied to automatically obtain the optimal performance trade-offs of integrated inductors. A methodology is presented that combines a multi-objective evolutionary 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 technology. The methodology is illustrated with a complete set of examples where different inductor trade-offs are obtained.
