Abstract
A multiplication and addition circuit multiplies each of a plurality of analog voltages by a corresponding digital multiplier and then adds up the products. First, each bit corresponding to each of the multipliers is multiplied with the corresponding analog voltage. Then, the products for each bit of the multiplier are added. The results are weighted by each bit weight and the weighted values are added. The multipliers are rotated so that there is the number of data transmission errors is lowered.
