Fourth-order Mebius strip-type cellular neural network chaotic circuit

Abstract

The invention discloses a fourth-order Mobius band type chaotic circuit. The fourth-order Mobius band type chaotic circuit is characterized in that a third operational amplifier A<3>, a fourth operational amplifier A<4>, a sixth operational amplifier A<6> and a seventh operational amplifier A<7> of the fourth-order Mobius band type chaotic circuit form linear reversed-phase integrators, and output ends of the third operational amplifier A<3>, the fourth operational amplifier A<4>, the sixth operational amplifier A<6> and the seventh operational amplifier A<7> are chaotic signal output ends X<1>, X<2>, X<3> and X<4> respectively; a first operational amplifier A<1> and a fifth operational amplifier A<5> form linear reversed-phase amplifiers; a second operational amplifier A<2> forms a nonlinear reversed-phase limiting amplifier; the reversed-phase integrator A<3> is connected with the amplifier A<1> and the reversed-phase integrator A<4>; the reversed-phase integrator A<4> is connected with the integrator A<3> and the amplifier A<5>; the reversed-phase integrator A<6> is connected with the integrators A<4> and A<7>; the reversed-phase integrator A<7> is connected with the integrator A<6>. The fourth-order Mobius band type chaotic circuit has the advantages that the fourth-order Mobius band type chaotic circuit is a chaotic circuit, accordingly, various waveforms, phase diagrams and chaotic evolution curves of the fourth-order chaotic circuit of a neural network can be outputted, and chaotic security communication systems can be formed.
