Abstract
In this work we propose a self-adaptive clock based on a ring oscillator as the solution for the increasing uncertainty in the critical path delay. This increase in uncertainty forces to add more safety margins to the clock period which produces a circuit performance downgrade. We evaluate three self-adaptive clock systems: free running ring oscillator, infinite impulse response filter controlled RO and TEAtime controlled ring oscillator. The safety margin reduction of the three alternatives is ...
