摘要：

Chaos is observed from a fourth-order autonomous circuit inspired by Chua's circuit and obtained by replacing the active symmetric nonlinear resistor (Chua's diode) with a parallel combination of a frequency dependent negative resistor (FDNR) and a general-purpose signal diode. Accordingly, nonlinearity is introduced by a passive device with antisymmetric current-voltage characteristics whereas activity is transferred to the FDNR. The observed chaotic attractor has similar dynamics to the Colpitts chaotic attractor and we show its topological equivalence to the well-known Rossler attractor. Experimental results, PSpice simulations and numerical simulations of the derived mathematical models are included.
