Abstract: A neuron simulation circuit and a neural network apparatus. The neuron simulation circuit includes an operational amplifier, a first resistive device and a second resistive device. The operational amplifier includes a first input terminal, a second input terminal, and an output terminal. The first resistive device is connected between the first input terminal or the second input terminal of the operational amplifier and the output terminal of the operational amplifier. The second resistive device is connected between the output terminal of the operational amplifier and an output terminal of the neuron simulation circuit. The second resistive device includes a threshold switching memristor, and a first terminal of the threshold switching memristor is electrically connected with the output terminal of the neuron simulation circuit. At least one of the first resistive device and the second resistive device includes a dynamic memristor.
