Abstract

The invention discloses a single-neuron chaotic circuit based on a time-delay neural network. The neuron circuit consists of an addition and integral operation circuit and an activation function circuit module, wherein the addition and integral operation circuit consists of an operational amplifier, a resistor and a capacitor; the excitation circuit module is composed of a summing circuit and first to fifth segment modules. The segmentation module is composed of an additive operation circuit and a voltage comparison circuit, wherein the additive operation circuit is composed of a relay and an operational amplifier. By giving an initial value and time delay, the chaotic oscillation phenomenon generated between the voltage x (t) and the time delay signal voltage x (t-tau) can be observed through an oscilloscope, and different chaotic phenomena can be observed when different initial values or time delay are set. According to the circuit, complex chaotic oscillation can be generated by a single neuron under fixed time lag, and the circuit is of great significance to application research of a chaotic neural network.

Description

technical field [0001] The invention belongs to the field of nonlinear circuit design, and relates to a new single neuron time-delay neural network chaotic system and its circuit. Background technique [0002] With the rapid development of chaos theory research, people's analysis and exploration of chaotic phenomena is not limited to the discussion of itself, and the combination of chaotic systems and various fields has gradually become the research direction of scholars, such as chaos economics, Chaotic secure communication, chaotic meteorology or chaotic neural network. However, many applications of chaotic systems need to be further developed and perfected.
