A method and apparatus for a linearized output driver and terminator is described. In one embodiment the method includes forming a gate electrode on a substrate, the portion of the substrate covered by the gate electrode defining a channel. The method further includes forming a first source/drain doped region on laterally opposed sides of the gate electrode in the substrate. The method also includes forming a spacer on laterally opposed sides of the gate electrode on the substrate. The method also includes forming a linearized drain contact region at a location within the first source/drain doped region sufficiently distant from the gate electrode to define a series resistor in the first source/drain doped region disposed between the gate electrode and the linearized drain contact area based on an expected resistivity of the source/drain doped region, the series resistor coupled electrically to the channel.
