  This paper proposes an innovative chaotic circuit based on Chua's oscillator.
It combines traditional realization of a non-linear resistor in Chua's chaotic
oscillator with a promising memristive circuitry. This mixed implementation
connects old research works that were focused on diodes with relatively new
research papers that are, now, concentrated on memristors. As a result, more
reliable chaotic circuit with an HP memristor is obtained that could be used as
a source of randomness. Dynamic behavior of the circuit is studied by obtaining
fft analysis, different chaotic attractors and Lyapunov exponent spectrum. The
results show that the addition of a memristor enhances chaotic behavior of the
circuit while maintaining the same power dissipation.
