Optimal RF design using Smart Evolutionary Algorithms
This paper presents an optimization algorithm that is able to significantly increase the speed of RF circuit optimizations. The algorithm consists of a series of consecutive evolutionary optimizations of the circuit itself and of a modeled version thereof. The speed increase arises from the difference in evaluation time between the real simulation and the fit evaluation. As circuit approximation, behavioral models are used instead of polynomial expressions, allowing to put some "design knowledge" into the optimization. gaRFeeld is a tool implementing this smart evolutionary algorithm for RF circuits. Finally some experiments performed with gaRFeeld are illustrated for the optimization of a Low Noise Amplifier
