Tracking unity gain for edge rate and timing control

摘要

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.
