Analog circuit design with a variable length chromosome
Shin Ando, Hitoshi Iba · 2002
This paper proposes a system of evolving analog circuits based on a variable length chromosome. Methods featured are the chromosome of a component list, the multi-stage evolution, and the pressure on the circuit size. A set of experiments are described to confirm the system's robustness, the scalability of a circuit, and the efficiency of time and the memory consumption. The first experiment shows the robustness supplied by the evolutionary method. The second one compares several types of chromosome implementation schemes. We also provide experiments to evaluate the multi-stage and scaling methods.
