Synaptic memristor bridge circuit with pulse width based programable weights in digit character recognition

Memristor bridge circuit linearly generates synaptic weights in the range [-1; 1]. A long width
pulse programs the synaptic weights and a short width pulse computes multiplication results in ANN model. Each digit is sampled by 10 times, forming 5x4 matrix. Thecharacter recognition rate achieves 100% for digits from 1 through 5 . 5%, 10%, and 15% noisy patterns is added to consider the recognition rate.
