a Designed circuit schematic for artificial vision system including proper counterparts corresponding to photoreceptors and synapses. b Measurement results of PSC at each node according to light intensity. From top to bottom: input pulse (Node 1), pulse with amplitude proportional to light intensity due to voltage division (Node 2), amplified pulse including gate offset voltage (Node 3), and PSC obtained at the shunt resistance (Node 4). c (i) EPSC trend correspond to the amplitude of gate input voltage. (ii) IPSC trend correspond to the amplitude of gate input voltage. d Schematic illustration of a light emitting source moving diagonally from the D1 region to the D9 region (left) and acquired PSC at each UDST within 3×3 array. e Visualized PSC extracted during each signal input sequence.
