Chaos computing: experimental realization of NOR gate using a simple chaotic circuit

Abstract

We report the experimental realization of a simple threshold controller, which clips chaotic dynamics to periods of different orders, in a continuous-time simple analog simulation type chaotic circuit. Further we use this technique to implement the fundamental NOR gate, thus providing a proof-of-principle experiment to demonstrate the universal computing capability to chaotic circuits. The advantage of this particular realization is that it may be simply implemented with monolithic integrated circuits for low-voltage or low-power applications, and thus is of considerable practical significance.
