10GHz clock distribution using coupled standing-wave oscillators

Abstract

A global clock network comprised of coupled, standing-wave oscillators is prototyped in a 0.18/spl mu/m 6M CMOS process. The clock network operates from 9.8 to 10.5 GHz with 0.6ps skew and contributes only 0.5ps jitter when referencing a clock source with 1.4ps rms jitter.
