Synapses are responsible for connecting neurons and communicating spike signals between them. A synapse receives spike voltages from the output of its pre-synaptic neuron. It produces a current based on a weight value. Then it feeds this weighted current to its post-synaptic neuron [32, 65–71, 73–75, 78, 79]. A CMOS synapse circuit model for Spiking Neural Network (SNN) is shown in Fig. 6.1. The CMOS synapse circuit design ensure that all transistors are working at the subthreshold level [30, 76, 77].

摘要

Synapses are responsible for connecting neurons and communicating spike signals between them. A synapse receives spike voltages from the output of its pre-synaptic neuron. It produces a current based on a weight value. Then it feeds this weighted current to its post-synaptic neuron [32, 65–71, 73–75, 78, 79]. A CMOS synapse circuit model for Spiking Neural Network (SNN) is shown in Fig. 6.1. The CMOS synapse circuit design ensure that all transistors are working at the subthreshold level [30, 76, 77].
