Simple chaotic oscillators with diode bridges

Two similar simple chaotic oscillators are described as an autonomous circuit that uses four energy storage elements: a 2 linear passive inductors and a 2 linear passive capacitors for first oscillator and one linear passive inductor and 3 linear passive capacitors for second oscillator. The other element is a negative resistance and nonlinear diode-bridge used as a memristor. The oscillators were simulated and results are shown. Main advantage of presented oscillators is simple construction and reliable function. These nonlinear devices can be used as a building block e.g. in chaotic sensors.
