Abstract:
1. A resonant clock driver of a clock distribution network, the resonant clock driver comprising: a first inductive resonance element electrically coupled to a clock node of the resonant clock driver via a first switch, wherein, upon being enabled via selection of the first switch, the first inductive resonance element is configured to cause the resonant clock driver to resonate at a first frequency corresponding to an inductance value of the first inductive resonance element; a second inductive resonance element electrically coupled to the clock node via a second switch, wherein, upon being enabled by selection of the second switch, the second inductive resonance element is connected in series with the first inductive resonance element causing the resonant clock driver to resonate at a second frequency corresponding to a sum of inductance values of the first inductive resonance element and the second inductive resonance element; and one or more drive elements electrically coupled to the clock node, the one or more drive elements configured to receive and propagate a reference clock of the clock distribution network.
