A new high performance realization of mixed-mode chaotic circuit using current-feedback operational amplifiers. (English) Zbl 1057.94518

Summary: A new CFOA-based realization of a mixed-mode chaotic circuit, which has both autonomous and nonautonomous chaotic dynamics, is proposed. The main purpose of this study is to improve the performance of mixed-mode chaotic circuits using only CFOAs. CFOA-based topologies used in this realization enable the simulation of ideal floating and grounded inductances. This modification provides the designer with wideband chaotic signals for secure communication systems. In addition to this major improvement, a CFOA-based nonlinear resistor was used in the new realization of a mixed-mode chaotic circuit. The usage of CFOA-based inductance simulators and nonlinear resistor in the circuit’s structure reduces the component count and provides isolated outputs.
