“…14 shows I in as a function of time under continuous pre-synaptic input signal. When the presynaptic input is continuously applied to the synaptic device it undergoes transition from short-term to longterm potentiation [9] causing similar transition in I in as well which is transferred to post-synaptic neuron. This phenomenon is similar to long-term potentiation in biological synapse [13].…”

“…The interconnect circuit can receive signals from multiple presynaptic neuron circuits but for sake of simplicity only one pre-synaptic signal is shown active. The siliconbased floating-body synaptic transistor [9] is used as synaptic device in the circuit. The structure of the synaptic device is based on floating-body transistor to show short-term plasticity (STP) and have floating gate and back-gate to show long-term plasticity (LTP).…”

“…Along with that the circuit is enough design flexible over these previous neuron circuits. In addition, interconnect circuit between neurons using a silicon-based floating-body synaptic transistor [9] as a synaptic device has been proposed as well. The learning mechanism (both short-term and long-term) has been utilized by the interconnect circuit.…”

Abstract-We propose a simple and compact thyristor-based neuron circuit. The thyristor exhibits bi-stable characteristics that can mimic the action potential of the biological neuron, when it is switched between its OFF-state and ON-state with the help of assist circuit. In addition, a method of inter-neuron connection with synaptic devices is proposed, using double current mirror circuit. The circuit utilizes both short-term and long-term plasticity of the synaptic devices by flowing current through them and transferring it to the post-synaptic neuron. The double current mirror circuit is capable of shielding the pre-synaptic neuron from the post synapticneuron while transferring the signal through it, maintaining the synaptic conductance unaffected by the change in the input voltage of the post-synaptic neuron.

Abstract-In the previous work, we have proposed an integrate-and-fire neuron circuit and synaptic device based on the floating body MOSFET [1-3]. Integrateand-Fire(I&F) neuron circuit emulates the biological neuron characteristics such as integration, threshold triggering, output generation, refractory period using floating body MOSFET. The synaptic device has short-term and long-term memory in a single silicon device. In this paper, we connect the neuron circuit and the synaptic device using current mirror circuit for summation of post synaptic pulses. We emulate spike-timing-dependent-plasticity (STDP) characteristics of the synapse using feedback voltage without controller or clock. Using memory device in the logic circuit, we can emulate biological synapse and neuron with a small number of devices.Index Terms-Integrate-and-fire neuron circuit, synaptic transistor, spike-timing-dependent-plasticity, long and short-term memory, floating body MOSFET

In this paper, a synaptic transistor based on the indium zinc oxide (IZO)-hafnium oxide (HfO 2) thin film structure was demonstrated. Blue light pulses (470 nm) were used as the presynaptic stimulus, the IZO channel was used as the postsynaptic membrane, and the HfO 2 electrolyte film was regarded as the synaptic cleft. The synaptic transistor exhibited the behavior of paired-pulse facilitation. With different light power densities, the channel current of the transistor can be regulated to different levels, corresponding to different synaptic weights. In addition, the transistor showed the brain's memory behaviors including the short-term memory and the transition from the short to the long term memory. The synaptic behaviors of the transistor can be explained by the trapping and releasing processes of the photo-generated carriers.
