Abstract
An output driver that includes a pull-up network comprising a first plurality of resistive branches forming a first R-2R resistive ladder structure, wherein the resistive branches of the pull-up network are coupled to a high voltage supply through pull-up switching transistors. The output driver may further include a pull-down network comprising a second plurality of resistive branches forming a second R-2R resistive ladder structure, wherein the resistive branches of the pull-down network are coupled to a low voltage supply through pull-down switching transistors. The output driver includes a control circuit to selectively activate or deactivate each of the first plurality of resistive branches and to selectively activate or deactivate each of the second plurality of resistive branches.
