Abstract
This invention relates to adaptively compensating for variations in integrated chip circuitry due to delays caused by multiple thresholds. The multi-threshold adaptive dynamic scaling system disclosed compensates for normal on-chip variations which affect system process and voltage variability, as well as overall performance. This system regulates a voltage control and provides high voltage thresholds, regular voltage thresholds, and low voltage thresholds to compensate for threshold voltage variations.
