Abstract

A semiconductor circuit including a first subcircuit, at least a second subcircuit, and power management circuitry. The power management circuitry is operable for estimating a metric indicative of a momentary supply voltage present at the first subcircuit based on a power supply current of the first subcircuit and a cross current flowing between the first subcircuit and the second subcircuit.
