This work proposes an amorphous indium-gallium-zinc-oxide (a-IGZO) thin-film transistors (TFTs)-based neuron circuit for artificial neural networks. By using the threshold voltage (VTH) compensation method, the proposed circuit prevents the inaccurate output of the activation function caused by the threshold voltage (VTH) variation due to fabrication fluctuation.
