Study of chaos based on single electron device

Chua′s circuit in structure of cellular neural networks is realized by the hybrid device of single electron transistor and metal oxide semiconductor, named SETMOS. Then single scroll and double scrolls are obtained. SETMOS transconductance amplifier and SETMOS voltage comparator are designed, and the double-scroll-like chaotic circuit built of SETMOS is proposed. The double-scroll-like chaos attractor is verified by simulation. All the simulation results show that the designed circuits have the characteristics of simple structure and low power dissipation, and they can further improve the density of integrated circuits. It also provides a new method for the chaos to be used in engineering.
