  • Tracking unity gain for edge rate and timing control
    Patent number: 7218148
    Abstract: In general, in one aspect, the disclosure describes an apparatus for calibrating signals. The apparatus includes a unity gain detector to traverse a gain curve of an output buffer circuit to determine unity gain voltages associated with unity gain crossover points on an input voltage ramp. The apparatus further includes a pre-boost circuit to apply the unity gain voltages to at least one input/output buffer within the output buffer circuit.

  • Method and apparatus for high frequency data transmission and testability in a low voltage, differential swing design
    Patent number: 7057672
    Abstract: A high frequency data transmission circuit including design for testability (DFT) features. An integrated circuit includes core control logic to provide a data signal and output drive logic including a local data latch and a transmitter. The data latch receives the data signal and provides true and complementary forms of the data signal to the transmitter over symmetrical signal paths. The transmitter provides an output signal to an external receiver.
