Summary :

In this paper, a novel chaos circuit with long working-life is proposed. The proposed circuit consists of NMOS-coupled discrete-time chaotic cell circuits. By employing chaos synchronization phenomenon, the proposed circuit can achieve long working-life. Since the proposed circuit is less susceptible to breakdown, the rate of the acceptable product for chaos IC can be improved. Furthermore, thanks to the coupling by using NMOSFET's, the loss of the connection line between chaotic cell circuits can be controlled electronically. Therefore, the proposed system designed by using switched-current (SI) techniques is useful as an experimental tool to analyze chaos synchronization phenomena. The validity of the proposed circuits is confirmed by computer simulations and experiments.
