Abstract
In an embodiment, an integrated circuit includes a clock tree circuit and logic circuitry that is clocked by the clocks received from the clock tree circuit. The logic circuit is powered by a first power supply voltage. The integrated circuit includes a voltage regulator that receives the first power supply voltage and generates a second power supply voltage having a magnitude that is lower than the magnitude of the first power supply voltage by a predetermined amount. The second power supply voltage may track the first power supply voltage over dynamic changes during use, either intentional changes to operating state or noise-induced changes. The second power supply voltage may be used to power at least a portion of the clock tree.
