Abstract
A non-crystalline silicon--preferably a-Si:H--active device for use in a large-scale hardware implementation of an artificial neural network system having an analog and digital mixed morphology. A plurality of a-Si:H thin-film transistors (TFTs) implement addition, multiplication and weighting functionality and are arranged in a highly-connected morphology with other active and passive semiconductor elements. Electrical signals are selectively applied to metal plates and light-emitting devices in order to locally or globally alter the threshold characteristics of the TFTs.
