Analog Circuit Design with Variable Length Chromosomes

This paper proposes a system of evolving analog circuit based on a variable length chromosomes. It should confirm the system’s robustness, circuit scalability, and effieciency on time and memory comsumption. Methods featured here are chromosomes of component list, multiobjective evolution, and two-stage evolution. Set of experiments are shown in this paper. First experiment reconfirms the robustness supplied by the evolutionary method. Second compares several types of chromosome implementation. There are also experiments to evaluate the two-stage and scaling method.
