1. An apparatus, comprising:

  • an output segment comprising a first plurality of secondary switches configured to selectively connect a plurality of conductive paths to an output;

    a main branch comprising a plurality of unit resistance elements, wherein each of the plurality of unit resistance elements comprises a respective resistor and a respective switch;

    a first edge segment comprising a second plurality of secondary switches configured to selectively connect at least one conductive path of the plurality of conductive paths to at least one unit resistance element of the plurality of unit resistance elements;

    a second edge segment comprising a third plurality of secondary switches configured to selectively connect at least one conductive path of the plurality of conductive paths to at least one unit resistance element of the plurality of unit resistance elements; and

    a sub-segment comprising;

    a plurality of terminal resistors, wherein at least one of the plurality of conductive paths is connected to at least one of the plurality of terminal resistors; and

    a plurality of main switches configured to selectively connect at least one terminal resistor to at least one unit resistance element of the plurality of unit resistance elements,wherein a single switch design is used in common for the plurality of main switches and the respective switches of the plurality of unit resistance elements.
