Rich Variety of Bifurcation and Chaos in a Simple Non-Source Free Electronic Circuit with a Diode

A very simple nonlinear parallel forced LCR circuit is proposed as Balamurugan-Sengodan-Danie1 (BSD) circuit includes linear inductors, capacitor, locally active resistor and a diode driven by a sinusoidal voltage source. By varying the amplitude of the external signal, we identify the familiar quasiperiodic routes to chaos as well as period doubling sequences, windows, and so on. The performance of the proposed system is demonstrated experimentally and proved with Poincare map results.
