Global clock distribution using standing wave resonant on transmission lines

In this paper, an X-tree clock distribution typology has been applied, a two stage, 7.5 mm * 7.5 mm dimension standing wave resonant clock distribution network can perfectly convey clock signals everywhere on to the chip without taking up much of the chip area (around 1.28mm², which is 2.2% of the total chip area), and dissipating 51.75 mW power. The clock jitter is 1.86ps and almost zero clock skew.
