This paper presents a novel method for systematic design of a composite cost function for typical analog circuit sizing optimization problems involving multiple criteria. A non-linear normalization strategy for objective functions has been proposed and has been shown to be better than the traditional linear normalization functions. A Hierarchical Cost Tree Mutation based dynamic weight adjustment algorithm has been developed, which combines the designers? problem specific knowledge with the dynamic solution state in the current iteration to decide the weights in the next iteration. Experiments on a typical Switched Capacitor analog integrator circuit in
