The simple 3D-chaotic dynamics of an autonomous oscillator circuit was studied by measuring its responsible in the form of phase-portrait, power spectrum and chaotic time series. The new realization combines attractive features of the current feedback op-amp operating in both voltage and current modes to construct the active linear negative conductance. The component count is reduced and the chaotic spectrum is extended to higher frequencies. In addition, a buered and isolated voltage output directly representing a state variable is made available. The circuit consists of just three linear elements (two capacitors and one inductor), one linear negative conductance and two ideal diodes. The power spectra are presented to conrm the strong chaotic nature of the oscillations of the circuit. The performance of the circuit is investigated by means of experimental simulation and numerical conrmation of the appropriate dierential equations. The features of the obtained results are respected for various engineering systems such as chaos communication systems with robustness against various interferences.
