PROGRAMMABLE IMPULSE NEURAL CIRCUITS

Impulse neural networks use pulse sequences to communicate instantaneous neuron activation levels. This paper describes CMOS electronic circuits, which emulate natural neurons at a more detailed level than that typically employed by artificial neural network models. A pulse-firing circuit which realizes general short-term neuron dynamics is discussed. Both fixed and programmable synapse circuits for realizing long-term dynamics are also described. Together, these establish the basic structures required for the implementation of programmable impulse neural networks.
