description A method and apparats for undervoltage detection and correction is disclosed. An IC includes sensors implemented in various functional circuit blocks. The sensors are implemented using ring oscillators, and may be characterized by a polynomial. The sensors are used to monitor a supply voltage provided to a corresponding functional unit. The sensors provide information indicative of the voltage on the supply voltage node over successive clock cycles. Comparison circuitry may be used to compare the detected voltage to one or more voltage thresholds, while delta comparison circuitry may be used to determine a slope, or rate of change of the voltage. Based on comparisons performed by the comparison circuitry and the delta comparison circuitry, control circuitry may determine if one or more voltage correction actions are to be taken in order to bring the voltage on the supply node into a specified range.
