Chaotic Admittance with Analog Multipliers

This brief paper focuses a design problem towards two-terminal device with unique property: chaotic or non-chaotic input current flows through this device depending on amplitude and frequency of the input harmonic driving voltage. Existence of chaos is proved numerically by means of two-dimensional colored plot of the largest Lyapunov exponent as a function of shape of input voltage signal. Gallery of the oscilloscope screenshots shows good agreement between numerical integration process and real experimental measurement. Some further ideas and few practical applications of proposed two-terminal element are also given.
