Abstract
A semiconductor integrated circuit which is comprised of the following; a plurality of comparators which respectively compare analog values inputted for multiplication with individual reference voltages respectively, multiplication means which controls values outputted from those plural comparators by applying signals corresponding to digital values inputted for multiplication and outputs the product of the values outputted from those plural comparators and the digital values, and a complement operation circuit which converts the value outputted from multiplication means into complement when the digital value is negative.
