Abstract:
1. A clock driver comprising: a resonance element electrically coupled to a clock node of the clock driver, the resonance element configured to enable the clock driver to operate in a resonant mode; a drive element electrically coupled to the clock node, the drive element configured to receive and propagate a reference clock of a clock distribution network based on a logical input signal; a mid-point supply node configured to provide a power supply to the resonance element; a first switch element, wherein a first end of the first switch element is electrically coupled to the mid-point supply node and a second end of the first switch element is electrically coupled to a first end of the resonance element; a second switch element connected in parallel to the resonance element, wherein a first end of the second switch element is electrically coupled to the first end of the resonance element and a second end of the second switch element is electrically coupled to a second end of the resonance element; wherein the clock driver is configured to selectively operate either in a resonant mode or a non-resonant mode based on an operating state of the first switch element and the second switch element, wherein:
