  • Dual rail time borrowing multiplexer
    Patent number: 6891400
    Abstract: A Dual Rail Time Borrowing Multiplexer (DTBM) generates a dual rail output from a single rail input with a one gate equivalent delay using a negative set up time. In one embodiment, a multiplexer includes a cross-coupled differential domino circuit coupled to a transistor array and to a data input and an enable input through a first and second circuit. The multiplexer outputs a dual rail output corresponding to a selected data input with a one gate equivalent delay using a negative set up time.
    Type: Grant

  • Dual rail time borrowing multiplexer
    Publication number: 20040217779
    Abstract: A Dual Rail Time Borrowing Multiplexer (DTBM) generates a dual tail output from a single rail input with a one gate equivalent delay using a negative set up time. In one embodiment, a multiplexer includes a cross-coupled differential domino circuit coupled to a transistor array and to a data input and an enable input through a first and second circuit. The multiplexer outputs a dual rail output corresponding to a selected data input with a one gate equivalent delay using a negative set up time.
