Patent ID: 8689023

Claim:
A digital logic controller for regulating a voltage of a system on chip, the digital logic controller comprising: a first input for receiving a first signal, the first signal being a reference signal and having a first property that is at least substantially constant over a range of operating conditions of the system on chip; a second input for receiving a second signal, the second signal having a second property that is indicative of an operating condition of the system on chip, the second property being variable over the range of operating conditions of the system on chip; an output; and a comparator for comparing the first property of the first signal and the second property of the second signal, wherein based on the comparison, the digital logic controller outputs to a voltage regulator, via the output, a regulation signal for regulating the voltage of the system on chip at or near a target voltage a predetermined amount higher than a minimum operating voltage of the system on chip, wherein the predetermined amount includes a worst case voltage drop in the System on chip due to peak current consumption.
