1.1 to 1.6GHz distributed differential oscillator global clock network

A distributed differential oscillator global clock network using on-chip spiral inductors is designed in a 0.18 /spl mu/m 1.8V CMOS technology. The 2mm/spl times/2mm resonant clock network has a tank Q of 4.3, achieves more than an order of magnitude less jitter than a conventional non-resonant tree-driven-grid global clock network, and uses almost three times less power.
