1. An apparatus comprising:

  • a phase control circuit comprising,a differential current generator having a differential output node configured to provide a differential drive current;

    a current conversion circuit connected to the differential output node configured to receive the differential drive current through saturated input Field-Effect Transistors (FETs), the saturated input FETs connected to triode mirroring FETs, the triode mirroring FETs configured to generate linearized current drive signals through first and second output drive nodes; and

    ,a phase interpolator circuit having a first phase driver circuit configured to receive a first phase of a reference signal, the first phase driver circuit connected to the first output drive node, and a second phase driver circuit configured to receive a second phase of the reference signal, the second phase driver circuit connected to the second output drive node, and configured to generate a phase interpolated reference signal.
