Abstract :
This paper proposes a 0.5-V LC-VCO with a frequency extension circuit to replace ring oscillators for ultra-low-voltage sub-1ps-jitter clock generation. Significant performances, in terms of 0.6-ps jitter, 50MHz-to-6.4GHz frequency tuning range with 2 bands and sub-1mW PDC, indicates the successful replacement of ring VCO for the future 0.5-V LSIs and power aware LSIs.
