Abstract
Systems and methods disclosed herein provide for effectively eliminating the rotational and static phase skews between the in-phase (I) and quadrature (Q) clocks generated by phase interpolators in decision feedback equalizer based receivers. Embodiments of the systems and methods provide for (i) a ring oscillator that eliminates the rotational phase skews and (ii) a plurality of clock mixers that eliminate the static phase skews.
