Novel chaotic oscillator configuration using a diode-inductor composite

Abstract

A general sinusoidal oscillator configuration is designed and then modified for chaos using a second-order nonlinear grounded diode-inductor composite. The configuration has an operating frequency that can be electronically tuned by varying the gain of an inverting amplifier stage. In addition to this amplifier, a single positive-type second generation current conveyor (CCII+), two noninverting integrators and two grounded resistors are required. The case where one of the integrators is replaced with an all-pass filter is investigated. Since the configuration is designed at a functional level, different circuit realizations are possible. Experimental results and PSpice simulations of a constructed implementation based on current feedback op amps are included. Numerical simulations of the derived chaotic mathematical models using a piecewise linear approximation of the diode current-voltage characteristics are also shown.
