✦ Synopsis

In this paper, an inductorless CMOS realization of ChuaÕs circuit [IEEE Trans. Circ. Syst.--I 1985;32:798] is presented. The circuit is derived from the dimensionless form of ChuaÕs circuit and can generate Rossler or double-scroll attractors by changing a single capacitorÕs value. Variables are represented in the current domain to facilitate adding or subtracting variables. New G m -C representation of the Chua diode as well as the Chua circuit are presented. The circuit can operate from supply voltage as low as AE1.5 V. Transistor-level simulation results using PSpice in 0.5 lm Mietec process are presented.
