Abstract

This paper proposes a novel chaos generator using the model of Josephson junction. Constructing an equivalent circuit of Josephson element by using an operational amplifier, we have made a chaos generator. The feature of this generator is to generate several kinds of oscillations as well as chaotic oscillations by only changing a DC bias current to the junction. In this paper, it is described in detail how to construct the circuit and what kind of oscillations is realized in the circuit. The experimental results of oscillation modes are compared with simulation results with a satisfactory agreement.
