| Zusammenfassung: | An ultra low power adder with sum synchronization which provides a power reduction method in the binary carry propagate adders by using a carry skip technique. The invention eliminates glitches at the adder outputs by preventing signal transitions at the sum outputs until the corresponding carry signals have reached their final values, which is achieved by adding a synchronization circuitry to the sum calculation path. |
