Abstract

The invention discloses a novel four-order neural network hyperchaotic circuit. First, second, third and fourth operational amplifiers A1, A2, A3 and A4 construct a linear inverting integrator; the output ends of the first, second, third and fourth operational amplifiers are chaotic signal output ends X1, X2, X3 and X4 respectively; a fifth operational amplifier A5 constructs a nonlinear inverting limiting amplifier; sixth and seventh operational amplifiers A6 and A7 construct a linear inverting amplifier; an inverting integrator A1 is connected with a limiting amplifier A5 and an amplifier A3 respectively; an inverting integrator A2 is connected with an integrator A3 and an amplifier A7 respectively; an inverting integrator A3 is connected with an amplifier A6; and an inverting integrator A4 is connected with an integrator A2 and an integrator A7 respectively. Due to the adoption of the four-order neural network hyperchaotic circuit, various waveforms, phase maps and chaotic evolvement curves can be output, and a hyperchaotic secret communication system can be constructed.
