  • Abstract
    In this brief, an efficient implementation of an 8-bit Manchester carry chain (MCC) adder in multioutput domino CMOS logic is proposed. The carries of this adder are computed in parallel by two independent 4-bit carry chains. Due to its limited carry chain length, the use of the proposed 8-bit adder module for the implementation of wider adders leads to significant operating speed improvement compared to the corresponding adders based on the standard 4-bit MCC adder module.
