Abstract

The invention discloses a multi-mode neuron circuit and a neuron realizing method. The circuit comprises a pulse generating circuit, and an auxiliary U-unit circuit which is connected with the pulse generating circuit. The pulse generating circuit is used for outputting a pulse sequence in a preset mode through function of a control signal and external applied voltage for realizing the corresponding neuron. The U-unit circuit is used for generating the external applied voltage and applies the external applied voltage to the pulse generating circuit. The multi-mode neuron circuit and the neuronrealizing method can effectively realize the neuron when realization of a large-scale pulse neural network system is required, thereby overcoming a problem of high operation difficulty in realizing different neurons through accurately adjusting offset voltage when realization of the large-scale pulse neural network is required.

Description

technical field [0001] The present invention relates to the technical field of artificial neural network, and more specifically, relates to a multi-modal neuron circuit and a method for realizing the neuron. Background technique [0002] Biological neurons can be divided into excitatory and inhibitory types. Among them, excitatory neurons can use the generated pulses to increase the membrane potential of subsequent neurons through excitatory synapses. Common excitatory neurons include RS, IB and CH; inhibitory neurons can use the generated pulses to pass through inhibitory neurons. The synapse will reduce the membrane potential of the subsequent neurons, and the common inhibitory neurons are FS and LTS. Furthermore, according to the difference in output under step current input, biological neurons can be divided into impulse neurons and burst neurons. Among them, RS is a spiking neuron, while IB and CH are bursting neurons. RS-type neurons can fire spiking with adaptation...
