Abstract

A new chaos generator that uses the second generation current conveyor (CCII) as the active building block and produces a chaotic current output signal is introduced. The procedure of obtaining the generator by modifying a current mode sinusoidal oscillator using a nonlinear resistor of antisymmetrical current voltage characteristics is emphasised. The small input resistance associated with the CCII inverting input terminal is found to be responsible for stimulating the circuit´s chaotic nature. Experimental results, PSPICE simulations and numerical simulations of the derived mathematical model are included
