Abstract

The invention relates to a four-order conservative chaotic oscillator which comprises capacitors C1 and C2, inductors L1 and L2, resistors R1 and R2 and an operational amplifier U. The inductor L1 isconnected with the capacitor C1 in parallel. The positive electrode of the capacitor C1 is connected with the in-phase input end of the operational amplifier U, and the negative electrode of the capacitor C1 is grounded. The resistor R1 is connected between the inverting input end and the grounding end of the operational amplifier U. The resistor R2 is connected between the output end Vo and the inverting input end of the operational amplifier U. And the capacitor C2 and the inductor L2 are connected in series and then are connected between the output end Vo and the in-phase input end of the operational amplifier U.

Description

technical field [0001] The invention relates to the technical fields of circuit design, communication and information, in particular to a chaotic oscillator. Background technique [0002] Chaos is a complex motion phenomenon that exists widely in nature. It is usually generated by deterministic systems and can produce random-like behavior without external interference. Its long-term motion is unpredictable. Due to the good randomness of chaotic signals, it has received more and more attention in the fields of information security, such as chaos-based secure communication, encryption and decryption of streaming media, etc. [0003] Chaos can be divided into dissipative chaos and conservative chaos, that is, chaos generated by dissipative systems and conservative systems respectively. If the energy dissipation is not considered, only the volume dissipation is considered, and the system dissipation is zero, indicating that it is a conservative system. Classical chaotic system...
