Abstract
In an embodiment, a supply voltage envelope detector circuit is configured to detect a shape of the supply voltage over time and to compare the detected shape to expected shapes that indicate voltage droop events for which corrective action may be needed. The expected shapes may be predetermined based on one or more of: the design of the integrated circuit that includes the supply voltage envelope detector circuit; attributes of the power management unit (PMU) that is to generate the supply voltage for the integrated circuit; and/or attributes of the system that includes the integrated circuit. The shape of the voltage droop may experience little variation during use, and thus may be used to detect a droop event earlier and more accurately than a threshold-based mechanism, in some embodiments.
