Description: Passive analog filter optimization algorithm based on particle swarm optimization design method is easy to fall into local optimum, the slow convergence iterations, large amount of computation and stability is not good enough. Efficient parallel search proposed Drosophila optimization algorithm for the whole parameter space of the filter until the optimal parameter values, the simulation results show that the designed filter in the case of the same bandwidth accuracy and stop-band attenuation, faster computing speed and convergence performance.
