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.

Dual rail time borrowing multiplexer

A domino circuit topology that includes a dynamic circuit, logic circuit, and static circuit. The domino circuit includes a dynamic circuit, logic circuit, and static circuit coupled through a central node. The dynamic circuit includes a pre-charge circuit and a keeper circuit for pre-charging the central node and keeping the central node at its current voltage level. The static circuit provides a static output for the domino circuit. The logic circuit provides logical functions for input signals. In addition, the domino circuit can include an isolation transistor coupled between the central node and the logic circuit.
