Abstract
In this paper, an inductorless CMOS realization of Chua’s circuit [IEEE Trans. Circ. Syst. – I 1985;32:798] is presented. The circuit is derived from the dimensionless form of Chua’s circuit and can generate Rossler or double-scroll attractors by changing a single capacitor’s value. Variables are represented in the current domain to facilitate adding or subtracting variables. New Gm-C representation of the Chua diode as well as the Chua circuit are presented. The circuit can operate from supply voltage as low as ±1.5 V. Transistor-level simulation results using PSpice in 0.5 ?m Mietec process are presented. © 2003 Published by Elsevier Science Ltd.
