1. An apparatus, comprising:

  • an input implemented to receive a differential input signal that includes a first input signal and a second input signal;

    first and second switches;

    first and second inverting switches;

    a current source coupled between ground and a node that couples a first end of the first switch and a first end of the second switch;

    a resistor coupled between a second end of the first switch and a second end of the second switch; and

    an output implemented to output a differential output signal that includes a first output signal and a second output signal; and

    wherein;

    the first input signal is provided to the second inverting switch and the second switch such that the first input signal ensures that the second inverting switch is closed when the second switch is open;

    the second input signal is provided to the first inverting switch and the first switch such that the second input signal ensures that the first inverting switch is closed when the first switch is open;

    the first inverting switch couples between a power supply voltage and the second end of the first switch;

    the second inverting switch couples between the power supply voltage and the second end of the second switch;

    the first output signal is output from the second end of the first switch; and

    the second output signal is output from the second end of the second switch.
