Sequential multiobjective optimization for large-scale passive filter synthesis

We propose a generic method for handling coupling among subsystems in large-scale multiobjective analog circuit synthesis. It is based on sequentially solving multiobjective optimization problems for each subsystem. The approach is exemplified on a pure feasibility problem of black-box passive filter design for a communications application. A proof-of-concept for the proposed method is provided through simulation. The practical outcome is a well-selected set of alternative design choices that all fulfill the pre-specified filter design constraints.
