Genetic Optimization Algorithms In The Design Of Coupled Saw Filters
Ultrasonics Symposium, 2004 IEEE(2004)
Abstract
We have studied genetic optimization algorithms in the design of longitudinally coupled surface acoustic wave filters. We employ a genetic algorithm in the optimization of a symmetric filter structure with 14 simultaneously optimized parameters. The effect of several parameters of the algorithm on the convergence of the optimization is investigated. Our algorithm is compared to a modification of the "cut-and-paste" method often used in genetic optimization. Our results indicate that a genetic optimization routine is suitable for the design of coupled filters.
