The disclosure describes a phase-splitter/level shifter comprising a first MOS transistor has a drain coupled to the first output node and a source coupled to a feedback node through a source resistor and a gate. A second MOS transistor has a drain coupled to a second output node and a source coupled to the feedback node through a source resistor and a gate. A first operational amplifier has a non-inverting input coupled to a single-ended input node, and an inverting input coupled to a second reference current source, an output coupled to the gate of the first MOS transistor. A second operational amplifier has a non-inverting input coupled to a single-ended input node, an inverting input coupled to a first reference current source, and an output coupled to the gate of the second MOS transistor. A variable resistor is coupled between the source of the first and second MOS transistor.
