  This paper presents the dynamics of a practical equivalent of a smooth
memristor oscillator derived from Chua's circuit. This approach replaces the
conventional Chua's diode by a flux controlled memristor with negative
conductance. The central idea is to design a practical memristor based circuit
using electronic analogy in order to bypass problems related to the realization
of memristor equivalents. The amplitude and the frequency of the oscillations
are previously defined in the circuit design. The result is a robust and
flexible circuit without inductors, which is able to reproduce a rich variety
of dynamical behaviors. The proposed analogue circuit is successfully designed
and implemented, producing experimental time series, phase portraits, and power
spectra, which are corroborated by numerical simulations. The "0-1 test" is
also performed in order to verify the regular and chaotic dynamics on the
proposed analogue circuit.
