Problems solved by technology

Traditional Chua circuit such as figure 1 As shown, most of the negative resistance sub-circuits are built based on operational amplifiers, not only the structure is relatively complex, but also the speed of operational amplifiers limits the oscillation frequency of Chua's circuit
There are many ways to realize the negative resistance circuit, such as the tunnel diode, but the tunnel diode itself needs an operating point bias circuit, and the overall circuit is still relatively complicated.

Embodiment Construction

[0039] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] figure 1 It is a structural diagram of a common traditional chaotic oscillator circuit.

[0041] Such as figure 2 As shown, the chaotic oscillating circuit of the present invention includes a color ring inductance L, two chip capacitors C 1 、C 2 , a variable resistor R in the form of a plastic square multi-turn trimmer, and a six-inverter chip CD4069. The above components can be packaged in common components on the market, and CD4069 is a common CMOS six-inverter chip, which is supplied by many chip manufacturers. In the chaotic oscillation circuit of the present invention, only two inverters in CD4069 are used, which correspond to pins 1 to 4 of the chip, and the two inverters are connected end to end, forming the nonlinear negative resistance part in the Chua's circuit , located between the two ports B and C of th...

Abstract

The invention discloses a chaotic oscillating circuit comprising a color circle inductor, a resistor, two chip capacitors and a nonlinear negative resistance circuit, wherein the resistor is a variable resistor, the nonlinear negative resistance circuit is formed by connecting two inverters in parallel in a CMOS (Complementary Metal-Oxide-Semiconductor Transistor) hex inverter chip, and the two inverters are connected end to end. The chaotic oscillating circuit has simple structure and adopts easily-obtained components, thereby being easy to realize; meanwhile, the chaotic oscillating circuit presents chaotic oscillating phenomena difficult to be observed in daily life and has relatively higher oscillation frequency; and in addition, various chaotic phenomena and gradual changes among the various chaotic phenomena in double-eddy chaotic oscillation can be observed only by simply adjusting the value of the variable resistor.

Description

technical field [0001] The invention relates to chaos and nonlinear systems, in particular to a double vortex chaotic oscillation circuit. Background technique [0002] Since Lorenz, a professor at the Massachusetts Institute of Technology and one of the founders of chaos, published a paper entitled "The Butterfly Effect" in 1972, its conclusions are still talked about today, and more importantly, , which has inspired people's strong interest in chaos. Today, with the rapid progress of computer and other technologies, chaos has developed into a frontier science with far-reaching influence and rapid development. [0003] Chaos is also common in circuit systems. Since the discovery of chaotic circuits for more than ten years, the chaotic phenomena in circuits and their applications have aroused great research interest in the field of circuits and systems in the world, and many achievements have been made. There are many reasons why chaotic circuits become a research hotspot ...
