  • Multi stage slew control for an IC output circuit
    Patent number: 5013940
    Abstract: The transient voltage spike generated by the distributed inductance of the packaging wires on an IC chip is reduced by slowing the on-to-off switching speed of the output transistors. The longer switching time provides a longer dt in the di/dt current through the wires during turn off. A two stage slew control circuit controls the initial stage and final stage of the slew period with an initial fast stage to advance the start of output transistor turn off and a slow stage for extending the turn off slew period during the final stage of the slew period.
