Abstract: The chaotic circuit design is a prerequisite to chaotic communication,the chaotic encryption etc.Therefore the fundamental research and design of chaotic circuits are extremely significant.In this paper,a new method to design chaotic circuits is proposed,through which it becomes very simple and flexible to design chaotic dynamic systems in the 2D state space.The remarkable character of this design method is:we can choose complexity of the chaotic attractor as we need by combining the three kinds of modules,and the chaotic attractor can be easily implemented with a circuit or a integrate circuit.

Key words: chaos, chaotic signals, symbolic dynamics, topological horseshoes, random signals
