  The model of a memristor-based oscillator with cubic nonlinearity is studied.
The considered system has infinitely many equilibrium points, which build a
line of equilibria in the phase space. Numerical modeling of the dynamics is
combined with bifurcational analysis. It is shown that oscillation excitation
has distinctive features of the supercritical Andronov--Hopf bifurcation and
can be achieved by changing of a parameter value as well as by variation of
initial conditions. Therefore the considered bifurcation is called
Andronov-Hopf bifurcation with and without parameter.
