  • Elements to counter transmitter circuit performance limitations
    Patent number: 9407470
    Abstract: Embodiments of the invention are generally directed to elements to counter transmitter circuit performance limitations. An embodiment of an apparatus for driving data on a differential channel including a first output terminal and a second output terminal includes a differential driver circuit; and a first pre-driver and a second pre-driver, where each pre-driver has an output, wherein the first output terminal of the apparatus is coupled to the output of the first pre-driver, and the second output terminal of the apparatus is coupled to the output of the second pre-driver, where each pre-driver includes one or more capacitors, a first end of each capacitor being connected to the output of the pre-driver and a second end of each of the capacitors being connected to a sub-pre-driver circuit.
