Summary:
We have developed an autonomous neuromorphic system that can work with four-terminal Si-based synaptic devices. The symmetrical current mirrors connected to the n-channel synaptic devices constitute the synaptic connection and integration parts to express the excitation and the inhibition mechanism of neurons. The number and the weight of the synaptic devices affect the amount of the current flowing into the capacitor. The double-stage inverters controlling delay time and the NMOS with large threshold voltage (V_T) constitute the action-potential generation part. The generated action-potential is transmitted to the next neuron and simultaneously returned to the back gate of the synaptic device for expression of spike-timing-dependent plasticity.
