Abstract: | Originating from a sinusoidal oscillator circuit that employs the current feedback op amp (CFOA) as the active building block, a new chaos generator that utilizes a discrete nonlinear device of asymmetrical nonlinearity is proposed. Two different positions of the nonlinearity within the circuit structure are investigated. A slight modification incorporating the addition of a single resistor to the generator is shown to facilitate its tuning and affect the dynamics of its chaotic behavior. Experimental laboratory results agree well with PSpice simulations, and both are included. |
