In this paper the dynamic behavior of a fourth order nonlinear
circuit has been studied. The circuit consists of a N-type
nonlinear resistor RN, a negative conductance Gn
and a sinusoidal generator 
. The theoretical and experimental
phase portraits and spectrums are been presented, for various
values of the amplitude of the input signal, in the low frequency
area. The genesis and catastrophe of the Double-Bell strange
attractor have been observed. Finally, the Poincare diagrams are
been given and we are concluding about system's dynamic behavior.
Key words:
nonlinear dynamics, chaos, non-autonomous circuit,
Lyapunov exponent, double-Bell attractor
