Analog integrated circuits implementing chemical reaction-diffusion systems

摘要

We developed a method of constructing CMOS circuits that implement or imitate the behavior of chemical reaction-diffusion Systems. Most chemical reactions and diffusion phenomena can be implemented on a CMOS circuit by using analog multipliers. As an example, we designed a circuit that implement the Brusselator model. We confirmed by computer simulation that the designed circuit successfully mutates the dynamics of the model.
