Abstract
A supply voltage management system and method for an integrated circuit (IC) die are provided. The supply voltage management system includes one or more temperature sensing elements located on the IC die and configured to sense temperature of the die and to output a sensed temperature value for the die. A dynamic voltage controller is located on the die and is configured to receive the sensed temperature value for the die and to identify a technology process category of the die. Based on the sensed temperature value and the identified technology process category of the die, the dynamic voltage controller adjusts an output voltage to at least one circuit of the die.
