A novel pulse stream neuron circuit is presented whose output pulse width facilitates sigmoid activation to activate the function of neurons. The wide symmetrical dynamic range of this neuron ensures high noise immunity. The pulsed activation strategy provides a power efficient architecture, so the circuit has very low power dissipation. The simplicity of the circuit ensures its suitability for large-scale integration.
