Abstract

A digital logic controller for regulating a voltage of a SoC includes a first input for receiving a reference signal having a first property that is constant over a range of operating conditions of the SoC, and a second input for receiving a second signal that has a second property that is indicative of an operating condition of the SoC. The second property may vary over a range of operating conditions of the SoC. A comparator compares the first and second properties and the digital logic controller, based on the comparison, outputs to a regulation signal to a voltage regulator to regulate the voltage of the SoC at or near a target voltage that is higher than a minimum operating voltage of the SoC.
