To deeply understand neuromorphic electronic systems,a basic chemical synapse model is given by logistic Euler inverse mapping and transformation in tandem,3T-MOS triod-trigger-topology(3T3) is designed in sub-threshold region at 100 mV supply for compact synaptic circuit,and the power consumption of synapse in brain-circuitry(ion-bump-city) is compared with its five mimic blocks of HfOx/AlOx typed memristor,modified 2T-MOS-K+-bump circuit,3T3 synaptic circuit and 4T-Schmitt-oscillator based synaptic circuit,and Chua’s circuit on Power-delay-products’(PDP) levels.Above works will match searching for novel feature operators during pushing forward brain health microelectronics.
