Abstract
Disclosed herein are related to an integrated circuit to regulate a supply voltage. In one aspect, the integrated circuit includes a metal rail including a first point, at which a first functional circuit is connected, and a second point, at which a second functional circuit is connected. In one aspect, the integrate circuit includes a voltage regulator coupled between the first point of the metal rail and the second point of the metal rail. In one aspect, the voltage regulator senses a voltage at the second point of the metal rail and adjusts a supply voltage at the first point of the metal rail, according to the sensed voltage at the second point of the metal rail.
