Abstract
A constant slew rate amplifier has a precision internal slew rate control reference, that generates respective positive-going and negative-going voltages, associated with corresponding excursions in the input signal. These slew rate-defining voltages are decoupled from the line, making it possible to drive the line with an amplified output signal that faithfully follows the input signal and conforms with prescribed slew rate and rise/fall time specifications, irrespective of the capacitance of the line. In addition, the constant slew rate amplifier of the present invention is configured to minimize power dissipation during non-transitional signal conditions, while providing substantial current to rapidly drive the line from one state to another in accordance with the input signal.
