Multi-scroll chaos generator using current conveyors

A novel and simple technique is presented to realize a five scroll chaos generator circuit using second generation current conveyors. A novel sinusoidal oscillator is first realized using second generation dual output current conveyors (DOCCIIs) and grounded passive components, which is then employed for the implementation of the five scroll chaos generator. The technique basically employs a CCII based differentiator and a frequency dependent negative resistance (FDNR) composite to introduce the non-linearity into the sinusoidal oscillator to modify it as a chaos generator. The proposed chaos generator exhibits a five scroll chaotic voltage output. It enjoys attractive features such as use of DOCCIIs and grounded passive components. Moreover, due to the presence of all grounded passive components, the circuit is very much suitable for monolithic implementation in contemporary IC technologies. The proposed chaos generator is designed and verified using PSpice simulation and the results thus obtained confirm the theory.
