Abstract :
A 3.5GHz 8-phase all-digital clock generator is fabricated in 150nm CMOS to achieve scalable 1.7/spl times/ frequency-range and 9ps end-to-end time resolution measured at 1.6V and 110/spl deg/C. A closed-to-open loop control scheme enables 32mW open-loop power consumption, 300/spl mu/W at clock gate-off, zero-cycle response during clock re-enable, and <4% static phase error.
