摘要
A method and apparatus for providing a low power low voltage differential signaling driver are disclosed. In an example, a low voltage differential signaling driver circuit is described, comprising a first current source to provide current to a first differential pair of PNP transistors, a pair of transresistance amplifiers driven by a corresponding pair of transconductance stages, a second current source to provide current to a second differential pair of PNP transistors, and an output port having a common mode output voltage and a differential output voltage based on a state of the first differential pair of PNP transistors and the second differential pair of PNP transistors.
