The multiplier circuit includes an arithmetic circuit that multiplies a first current and a second current, a current generator that generates the first current, and a digital-analog converter that generates a reference current used by the current generator. The current generator includes a current mirror circuit (CM circuit) including first and second transistors, a third transistor, a switch that controls the current output, and first and second memory circuits. The reference current of the CM circuit is input to a drain of the first transistor, and a current which copies the reference current is output from a drain of the second transistor. A drain of the third transistor is electrically connected to the drain of the second transistor. The switch controls the first current output.
