WebA ripple-carry adder is a parallel adder created by connecting carry output of each full-adder with the carry input of the next higher-order full-adder. The input carry should occur first to produce the sum and output carry of any stage (a stage is one full adder); this causes a time delay in the addition process. 4 bit Ripple Carry Adder WebA binary ripple-carry adder works in the same way as most pencil-and-paper methods of addition. Starting at the rightmost ( least significant) digit position, the two corresponding digits are added and a result is obtained. A 'carry out' may occur if the result requires a higher digit; for example, "9 + 5 = 4, carry 1".
