Abstract: A power delivery sub-system included in a computer system employs a primary voltage regulator circuit that generates a primary supply voltage on a primary power supply node. The power delivery sub-system also includes multiple bypass voltage regulator circuits that source corresponding bypass currents to a local power supply nodes in an integrated circuit. The integrated circuit includes multiple circuit blocks coupled to corresponding ones of the local power supply nodes, and multiple local voltage regulator circuits coupled to the primary power supply node. When a voltage level of a given local power supply node drops below a threshold value, a corresponding local voltage regulator circuit sources a supply current to the given local power supply node.

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.

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.

Abstract: 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.
