Abstract
One embodiment includes a clock distribution system. The system includes at least one resonator spine that propagates a sinusoidal clock signal and at least one resonator rib conductively coupled to the at least one resonator spine and arranged as a standing wave resonator. The system also includes at least one transformer-coupling line. Each of the at least one transformer-coupling line is conductively coupled to an associated circuit and has a plurality of inductive couplings to the at least one resonator rib to inductively generate a clock current corresponding to the sinusoidal clock signal via each of the plurality of inductive couplings in an additive manner to provide functions for the associated circuit.
