Original Abstract Submitted

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.
