Four current-tunable chaotic oscillators in set of two diode-reversible pairs

Four current-tunable chaotic oscillators are presented in a set of two diode-reversible pairs. The first pair employs a floating-diode technique whereas the second pair employs a virtually-grounded-diode technique. Two chaotic attractors of a pair are 180°-rotated images of each other. Each oscillator consists of six basic electronic components which are minimal in a category of chaotic oscillators that exploit a capacitor-inductor-capacitor network, opamp(s), diode(s) and resistor(s). Current-tunable bifurcations are demonstrated.
