Abstract :
This paper investigates the adoption of LC-VCO to replace ring VCO for ultra-low-voltage sub-picosecond jitter clock generation in future 0.5-V LSI and power aware LSI. A 0.5-V LC-VCO using E-TSPC frequency divider with forward body bias technique is proposed and implemented. Significant performances, in terms of 0.6-ps jitter, 50 MHz-to-6.4 GHz frequency tuning range with 2 bands and sub-1mW PDC, have been achieved in the measurement results.
