Design of elliptic filters with phase correction by using genetic algorithm

The paper presents a general algorithm of designing elliptic filters with phase correctors. The proposed algorithm uses a genetic solver to adjust the corrector´s transfer function of a decent order minimizing filter´s non-linearities and thus increasing the design immunity for signal distortion. The solution was implemented in Matlab environment and investigated using Matlab built-in functions as well as HSpice circuitry analysis.
