The new breed of reconfigurable integrated circuits (ICs) offer switched-capacitor based analogue circuits whose functionality can be altered during run-time. Rapidly changing the functionality of an analogue circuit provides interesting opportunities for control systems. It also opens a large design space in which decisions have to be made regarding the frequency and form of reconfiguration. We present a bioinspired architecture to facilitate the automated search for circuits on these platforms, based on well-established evolutionary algorithms. Unlike previous attempts at evolving single solutions, our genomes contain multiple solutions and use feedback provided by the circuit output to trigger reconfiguration of the IC.
