“…Recent research results have demonstrated clock distribution networks based on transmission lines (TL) [8], [9], [10]. Here the "wires" are larger in size, operating in "LC-mode" with low loss.…”

“…A superior use of TLs was reported in [9] and [10] where the circuits achieve about 1 ps skews at 10 GHz, with very low power dissipation, while being capable theoretically to cover practical-size clocking regions. Both schemes use many coupled oscillators interconnected into two-dimensional grids.…”

“…Our new concept for TL-based clock distribution has equal capabilities for jitter and power dissipation performance as in [9] and [10] by similarity of construction, but unlike these techniques, it is an open-loop method (no oscillators) generating constant-phase and constant-magnitude clock signals simultaneously. In addition, it is a wide band design not requiring resonating inductors as in [11].…”

Abstract-We introduce a serial passive clock distribution technique allowing efficient and accurate skew removal at any arbitrary clock drop point. The passive transmission medium may be on-chip electrical transmission lines built in current IC technology or possible optical wave-guides in future developments. The proposed technique is naturally insensitive to practical loses and other non ideal effects and has the capability of covering large chip areas.

“…Traveling-wave clock distributions [1] use coupled transmission line rings to generate low-skew and low-jitter clocks, but must contend with nonuniform phase across the distribution. Standing-wave clock distributions have also been proposed at chip-level [2]. The distribution scheme attained low-skew and low-jitter clocks, but its amplitude varied spatially across the network.…”

This paper presents a new standing-wave clock distribution scheme utilizing an inductor loading technique. The scheme can distribute multi-ten GHz uniform-phase/amplitude global clocks over a whole chip. By loading an adequate inductor, the grid pitch can be made finer than that for the conventional standing-wave technique, and clock frequency can be designed to be independent of the grid pitch. We designed a 20 GHz 6 x 6 grid clock distribution network using a 0.18 µm CMOS technology. For all 36 clocks, low skew less than 1.3% of the clock period and low amplitude deviation of 2% were obtained from circuit simulation.
