Abstract
Electronic circuitry comprising operational circuits of active switching type requiring timing signals, and conductive means for distributing said timing signals to the operational circuits, wherein the timing signal distribution means includes a signal path that has different phases of a drive signal are supplied via active means at different positions about the signal path where that path exhibits endless electro-magnetic continuity without signal phase inversion or has interconnections with another signal path having different substantially unidirectional signal flow where there is no endless electromagnetic continuity between those signal paths and generally has non-linear associated circuit means where the signal path is of a transmission line nature.

An apparatus comprising:
- a differential transmission line in a closed loop, the differential transmission line including a first conductive trace, a second conductive trace, and an odd number of one or more cross-overs, wherein each of the one or more cross-overs is configured to reverse the polarity of a travelling wave propagating through the differential transmission line, wherein the polarity of the travelling wave reverses after the travelling wave completes a lap around the closed loop;
- and
- a plurality of regenerative devices electrically connected along a path of the differential transmission line, wherein the plurality of regenerative devices are configured to provide energy to the travelling wave to compensate for losses associated with the differential transmission line.
