Abstract
In some embodiments, a circuit is provided that comprises a dynamic circuit and a body bias circuit. The dynamic circuit has a keeper transistor. The body bias circuit is coupled to the keeper transistor and is configured to body bias the keeper transistor in accordance with a leakage associated with the dynamic circuit. Other embodiments are disclosed herein.
