An Area-Efficient Integrate-and-Fire Neuron Circuit with Enhanced Robustness against Synapse Variability in Hardware Neural Network

<div>Schematic of a biological neuron cell and its circuit analogy. A biological neuron consists of an axon, a soma, and dendrites (a). Basic relation of a leaky integrate-and-fire (LIF) neuron circuit and synaptic interconnections (b). Concept of the synaptic array accepting the spikes generated from the presynaptic neuron (c).</div>
