Current mode circuits: increasing the chances of evolution to find a way

Evolution of electronic circuits has been intensively investigated for the last five years. The main challenge of the area is the evolution of circuits for industrial applications and also to find methods to improve the performance of evolutionary computation in electronic circuit synthesis. The authors have been studying this problem using different approaches, such as new methods for circuit representation and fitness evaluation function. We describe in this paper experiments on the evolution of current mode circuits. Experimental results in the area of computational circuits suggest that the search space for this class of circuits is more amenable for evolution than their voltage mode counterparts. At the end of the paper we propose an application in the area of fuzzy control, which can provide benefits for the aerospace community, such as in applications for propulsion controlled aircraft.
