Abstract

A method of adjusting a voltage supply to an electronic device coupled to a wired communication link in accordance with a performance metric associated with the wired communication link. A voltage adjust signal is generated based on the performance metric. The voltage adjustment signal is then used for updating the voltage supply to the electronic device.

Description

technical field [0001] The subject matter disclosed herein relates generally to circuits for integrated circuits, and in particular to circuits and related methods for optimizing power supplies for electronic devices. Background technique [0002] An electronic system typically includes a plurality of electronic devices. Different devices are configured to perform different operations. At a given moment, certain devices may be operating at high speeds and thus consume more power than certain other devices in sleep mode. Similarly, a particular device may perform more operations at one moment and thus consume more energy than at a different moment. Other factors, such as manufacturing process variations, ambient temperature variations, or even aging differences between device components, can also cause power consumption to vary from device to device at the same time and the same device from time to time. As a result, both systems and individual devices have dynamic power r...
