  • Circuit and method for rapid power up of a differential output driver
    Patent number: 7394293
    Abstract: Output driver circuits and related methods. In one example, the output driver circuit includes a translator for converting the single ended data input signal into a pair of signals; a set of output transistors selectively controlled by the pair of signals; a cascode current source for providing a substantially constant current to the set of output transistors when the output transistors are active; and a dump path in parallel with the set of output transistors. A circuit portion for pre-charging the pair of signals to a pre-charged voltage between VCC and ground may also be provided.
