Abstract
An integrated circuit compensates for circuit aging by measuring the aging with an aging sensor and controlling a supply voltage based on the measured aging. The operating environment for the aging sensor can be set to reduce impacts of non-aging effects on the measured aging. For example, the operating environment can use a temperature inversion voltage. An initial aging measurement value which is the difference between an initial aged measurement and an initial unaged measurement can be stored on the integrated circuit. A core power reduction controller can use the measured aging and the stored initial aging measurement value to update a performance-sensor target value and then perform adaptive voltage scaling using the using the updated performance-sensor target value.
