Ultra-low power hybrid circuits
Abstract:
The present invention provides a solution to avoid the robustness problems of sub-threshold circuits by switching small parts of circuits to nominal-voltage only when they are being used, and switching them back to sub-threshold levels when the operation finishes. Such “hybrid sub-threshold” approach is capable of supporting ultra-low power operation without the disadvantages of sub-threshold circuits. Hybrid power saving mode for logic circuits provide significant power saving and fast recovery time without performance degradation.
