Abstract
A shifted-averaging VCO with precise multiphase outputs and low-jitter operation is presented in this paper. With the proposed shifted-averaging technique, the VCO could relax the phase errors and jitters caused by the mismatches among the active devices. Both the conventional and the proposed VCOs have been fabricated at the same die in a CMOS 0.35/spl mu/m 1P4M process. Compared to the conventional VCO, the proposed one could reduce the static phase errors among dell stages and improve jitters by a factor of 1.38.
