In this paper, a discrete-time CNN using 1-dimensional cell circuits with S stable points (S=2, 3, 4, ... ) is proposed. The circuit structure and the behavior of the proposed CNN is simple by exploiting discrete-time 1-dimensional circuits as the cell circuits. Since the proposed cell circuit takes as inuch as S of states, the proposed CNN can demonstrate the multiple-valued traveling wave phenomena. Furthermore, the proposed cell circuit is suitable for integration thanks to the circuit design by using switched-current (SI) techniques. The computer simulations are performed concerning a 2-dimensional CNN which is constructed with the proposed cell circuits. The 1-dimensional cell circuit with S stable points is designed by a standard CMOS process. Furthermore, the proposed cell circuit is built with commercially-available IC's. The experimental result is in close agreement with the simulation result. The proposed CNN is integrable by a standard CMOS technology.
