Abstract

The invention provides a three-order Lorenz 4 + 2 type chaotic circuit, comprising a first operational amplifier circuit A, a second operational amplifier circuit B and a third operational amplifier circuit C, wherein an aX input end and an a3 input end of the first operational amplifier circuit A and an output end of the first operational amplifier circuit A are connected with a bX input end and a b1 input end of the second operational amplifier circuit B, and an aY input end and an a2 input end of the first operational amplifier circuit A are connected with the output end of the second operational amplifier circuit B; a bY input end of the second operational amplifier circuit B is connected with a c2 output end of the third operational amplifier circuit C, and a c1 input end of the third operational amplifier circuit C is connected with an a1 output end of the first operational amplifier circuit A. The three-order Lorenz 4 + 2 type chaotic circuit provided by the invention has a simple circuit structure and can display various chaotic signals on an oscilloscope; and by means of some specific resistors, for example, after a resistor R4 or a resistor R6 is replaced by a variable resistor, then the chaotic characteristics of the chaotic signals can be changed.

Description

technical field [0001] The invention relates to the technical field of chaotic circuit optimization, in particular to a third-order Lorentz-like 4+2 type chaotic circuit. Background technique [0002] The Lorentz equation circuit is a circuit family, called the Lorentz equation-like circuit family, including the Lorentz equation circuit, Chen Guanrong equation circuit, Lu Jinhu equation circuit and a large number of other circuits. Its characteristic is that it can output phase diagram of . The existing circuit capable of outputting the phase diagram of upright butterfly wings is composed of 6 operational amplifiers and 2 analog multipliers, referred to as 6+2 circuits; other Lorentz-like circuit families are composed of 5 or more operational amplifiers Composition, the circuit structure is complicated, and it is easy to make circuit connection errors when conducting chaotic experiments, which wastes time and increases some unnecessary costs, which are the shortcomings of t...
