Abstract
Described is an integrated circuit with a driving amplifier that transmits a signal over a link (e.g. a wire) by raising and lowering a voltage on the link. A reference oscillator provides an error measure for the rate at which the voltage transitions between voltages, the slew rate. Slew-rate calibration circuitry adjusts the driving amplifier responsive to the error measure.
