Abstract: Disclosed is a simplified sigmoid function circuit which includes a first circuit that performs a computation on input data based on a simplified sigmoid function when a sign of a real region of the input data is positive, a second circuit that performs the computation on the input data based on the simplified sigmoid function when the sign of the real region of the input data is negative, and a first multiplexer that selects and output one of an output of the first circuit and an output of the second circuit, based on the sign of the input data. The simplified sigmoid function is obtained by transforming a sigmoid function of a real region into a sigmoid function of a logarithmic region and performing a variational transformation for the sigmoid function of the logarithmic region.
