SIGMOID FUNCTION CIRCUIT USED IN ARTIFICIAL NEURAL NETWORK

摘要

The present invention relates to a sigmoid function circuit used in a neuron of an artificial neural network. According to an embodiment of the present invention, the sigmoid function circuit used in the neuron of the artificial neural network may include a noise amplifier and a comparator. The noise amplifier may amplify thermal noise generated from a resistor. The comparator may repeatedly compare the results obtained by adding the amplified thermal noise with signals input to the neuron at a rising edge or a falling edge of a clock. According to an embodiment of the present invention, the sigmoid function circuit used in the neuron of the artificial neural network may include a comparator to perform a 1-bit ADC. Accordingly, the area and the power consumption of the artificial neural network may be reduced through the sigmoid function circuit having a small area.;COPYRIGHT KIPO 2018
