A CMOS neuron for VLSI circuit implementation of pulsed neural networks

This article presents a CMOS implementation of a biologically-inspired neuron. The neuron accommodates multiple excitatory and inhibitory inputs with digital weights and generates a pulse-width modulated output waveform of constant frequency based on the level of activation. The behavior of this implementation is demonstrated and it is shown that combinations of neurons form a complete logic set for realizing Boolean functions.
