Latest Patents

One of his latest patents is titled "Merged power delivery." This invention involves a power delivery sub-system included in a computer system that employs a primary voltage regulator circuit. This circuit generates a primary supply voltage on a primary power supply node. Additionally, the power delivery sub-system includes multiple bypass voltage regulator circuits that source corresponding bypass currents to local power supply nodes in an integrated circuit. The integrated circuit comprises multiple circuit blocks coupled to the local power supply nodes, along with local voltage regulator circuits connected to the primary power supply node. When the 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 that node.

Another significant patent is the "Method for power gating for wide dynamic voltage range operation." This device includes a circuit block coupled to a local power node and a power gating circuit that connects the local power node to a global power supply. In one embodiment, the power gating circuit consists of a first plurality of switching devices with a specific threshold voltage and a second plurality of switching devices with a different threshold voltage. This power gating circuit can isolate the local power node from the global power supply based on an isolation signal.
