1. An apparatus comprising:
a first circuitry to monitor a supply voltage and to generate a first code indicative of a digital representation of the supply voltage;
a second circuitry to receive the first code and to determine whether the supply voltage drooped, and to generate a droop indication if the supply voltage drooped;
a third circuitry to receive the first code or a version of the first code along with the droop indication, wherein the third circuitry is to generate a second code according to the first code or a version of the first code and the droop indication; and
power gates (PGs) coupled to an input supply voltage rail and an output supply voltage rail, wherein the PGs are controlled by the second code or a version of the second code.
