Abstract
An adaptive clock distribution (ACD) system with a voltage tracking clock generator (VTCG) is disclosed. The ACD system includes a tunable-length delay (TLD) circuit, to generate a TLD clock by adding a preselected delay to a root clock, and a voltage droop detector for detecting a voltage droop in a supply voltage. The VTCG is configured to generate a VTCG clock, wherein a frequency of the VTCG clock is finely tuned to one of two or more values to correspond to a magnitude of the supply voltage during the voltage droop. A clock selector selects the VTCG clock as an ACD clock to be provided to an electronic circuit during the voltage droop and the TLD clock as the ACD clock when there is no voltage droop detected.
