Abstract
An integrated circuit and method for providing a differential transmission line driver are disclosed. One embodiment of the differential transmission line driver comprises a current mode logic (CML) stage, and a cross-coupled n-channel enhancement type metal-oxide semiconductor field-effect transistor (NMOS) stage, wherein the cross-coupled NMOS stage provides a feedback current to the CML stage, where each output voltage of the differential transmission line driver is characterized by symmetrical rising and falling edges.
