Abstract

See full text

Embodiments of the present disclosure relate to managing power provided to a semiconductor circuit to prevent undervoltage conditions. A measured voltage value describing a measured supply voltage at a first subcircuit of a semiconductor circuit can be received, the measured voltage value having a first resolution. A selected metric indicative of a supply voltage present at the first subcircuit can be received, the selected metric having a second resolution higher than the first resolution. The selected metric is calibrated to obtain a calibrated metric when a transition of the measured voltage value occurs.
