Noise performance of single-electron depressing synapses for neuronal synchrony detection

Synchrony detection between burst and non-burst spikes is known to be one functional example of depressing synapses. Kanazawa et al. demonstrated synchrony detection with MOS depressing synapse circuits. They found that the performance of a network with depressing synapses that discriminates between burst and random input spikes increases nonmonotonically as the static device mismatch is increased. We designed a single-electron depressing synapse and constructed the same network as in Kanazawa´s study to develop noise-tolerant single-electron circuits. We examined the temperature characteristics and explored possible architecture that enables single electron circuits to operate at T > 0 K.
