Abstract

A phase interpolator is provided. The phase interpolator includes a plurality of first interpolation cells each configured to supply a first current to a common node of the phase interpolator. Further, the phase interpolator includes a plurality of second interpolation cells each configured to supply a second current to the common node. The second current is lower than the first current, wherein a sum of the plurality of second currents supplied to the common node by the plurality of second interpolation cells is substantially equal to the first current.
