摘要：
Apparatus for receiving a step-form input signal and providing a limited slew rate output signal in response thereto comprises an amplifier (26) that is operative to provide at its output terminal a current that is variable linearly between a maximum value of one polarity and a maximum value of the opposite polarity when the potential of its input terminal relative to its output terminal varies within a predetermined range. The magnitudes of the two maximum values are dependent on the magnitude of a control signal applied to a slope-control terminal (31) of the amplifier (26). The apparatus also comprises a resistor (34) connected between the output terminal of the amplifier and an output terminal of the apparatus, and a capacitor (42) connected between the output terminal of the apparatus and a reference potential level.
