1. A slew rate control system for a circuit, comprising:

  • a temperature sensitive device adapted to generate a temperature signal;

    a temperature dependent current source adapted to generate a first current source signal;

    a temperature independent current source adapted to generate a second current source signal; and

    a slew rate controller adapted to activate in response to said temperature signal when said temperature exceeds a first threshold, said slew rate controller further adapted to generate a slew rate control signal by adjusting a slew rate as a function of said temperature signal, said slew rate controller further adapted to activate said temperature dependent current source in response to said slew rate control signal.
