ABSTRACT:
An analog circuit which performs weighting and thresholding for a neural network. Each neuron of the neural network includes an operational amplifier receiving an input signal, the output of which is connected to a transistor. The transistor conducts only when the output exceeds a predetermined value thereby providing a threshold function. The output of the transistor is connected by a variable resistance to other inputs of other neurons. The output of each operational amplifier thereby corresponds to a weighted version of the input signal, which is adjusted for threshold and is also dependent on other neurons of the network.
