An output clock frequency of an adaptive oscillator circuit changes in response to noise on an integrated circuit power supply line. The circuit features two identical delay lines which are separately connected to a regulated supply and a droopy supply. In response to noise on the droopy supply, the delay lines cause a change in the output clock frequency. The adaptive oscillator circuit slows down the output clock frequency when the droopy supply droops or falls below the regulated supply. The adaptive oscillator circuit clamps the output clock frequency at a level determined by the regulated supply when the droopy supply overshoots or swings above the regulated supply.
