This paper presents a new ultra-low power high-speed single-clock-cycle binary comparator. It is based on a novel parallel-prefix algorithm which drastically reduces the switching activity of the internal nodes of the circuit. When implemented by using the ST 90nm-1V technology, the proposed 64-bit comparator exhibits an energy dissipation of only 0.77μW/MHz and a delay of 258ps. With respect to a recently published low-power high-speed parallel-prefix adder, the proposed design shows an energy… CONTINUE READING
