Claim Text:
1. A supply voltage regulation system, comprising: an integrated circuit having a ground pad coupled to a ground grid incorporated on said integrated circuit and a having a power pad coupled to a power grid incorporated on said integrated circuit; a temperature sensor provided on said integrated circuit that provides a temperature sense signal indicative of a die temperature of said integrated circuit; a scaling resistor having a first end coupled to said power grid and having a second end coupled to a feedback node; a voltage to current converter having a first input coupled to said ground pad, having a second input coupled to a hot point of said ground grid, and having an output for coupling to said feedback node; a voltage regulator amplifier having a first input receiving a reference voltage, having a second input coupled to said feedback node, and having an output for driving a supply voltage to said power pad of said integrated circuit; and a temperature scaling circuit having an input receiving said temperature sense signal and having an output coupled to said feedback node, wherein said temperature scaling circuit drives a scaling current to said scaling resistor via said feedback node to adjust said supply voltage based on said temperature sense signal.
