Abstract: Digital low-dropout micro voltage regulator configured to accept an external voltage and produce a regulated voltage. All active devices of the voltage regulator are digital devices. All signals of the voltage regulator, except the first voltage and the regulated voltage, may be characterized as digital signals. Some active devices of the voltage regulator may be physically separated from other active devices of the voltage regulator by active devices of non-voltage regulator circuitry.

Abstract: Introduced herein is an improved technique of recovering system frequency margin via distributed CPMs. The introduced technique creates and distributes multiple sets of always sensitized critical path replicas across a chip and monitors them for timing failure. The introduced technique takes feedback from these critical path replicas and dynamically boosts the clock frequency of the chip to remove the margin. The introduced technique provides more accurate and more comprehensive coverage of a chip performance.
