#$%^&*AU2020101601A420200910.pdf#####ABSTRACT This invention discloses a multi-memristive and multi-wing chaotic system circuit that is composed of four channel circuits: the first channel circuit is consisted of an inverter U1A, an inverted integrator U2A and inverter U3A, a multiplier Al and a resistor. The second channel circuit is composed of an inverter UlB, an inverting integrator U2B and an amplifier U3B, a multiplier A2, and a resistor. The third channel circuit is composed of the inverter U1C, the inverting integral integrator U2C and an oscillator U3C, the multiplier A3 and the resistor. The fourth channel circuit is composed of an inverter UlD, an inverted integrator U2D, multipliers A4 and A5, an addition circuit, and a resistor. In this invention, the memristive chaotic system is extend to a plurality of memristors that acts on the chaotic circuit, which is able to generate multi-wing chaotic attractors, and the dynamic behaviour of the system is more complex. The invention provides a novel method for applying a memristor to a multiwing chaotic circuit, and the generated chaotic signal is used in the fields of communication security, information encryption and the alike.-1/15R1 R21 C1 R4 A1 x -'M A21.7kn 10 10nF 10kn : 13 11 - 16 R20 U2A 3 1kn 10kW 20R5 -,2 U3A 0.1 1Memristive 0 x+0k circuitA 100kn 0 + -x A2 R5 R19 C2 R z -y -v vr x X ~2 r_U110F0k 0.1 V/V 0 V 1kQ 1R8 e U2B 7 cicit B y 10 1 -Z _ s c3- R14 A3 20k.0 10kn 2 U1C2 R16 10nF 10I 0.1 V/V 0 V 1knQ 3 U3CR Memristive 0 z 10k circuit C 100knl +F -z R23 C4 10kQ R26 R22 UID 10nF kI R2 7 1 IC=0.1V A4 AS50k y R24 U2D1 10kI - 90 x 61 R25 63 U3 --0.1 V/V 0 V 0.1 V/V 0 V 33.3k (A, B,C) (y,-z,-x) 4 5TFigure 1
