Abstract: Systems and methods for operating a driver circuit are described. In a first region of a transition from an input signal to an output signal, a circuit can control a slew rate of the output signal to a first rate. The first region can terminate prior to the output signal reaching a predefined threshold voltage. In a second region of the transition, the circuit can reduce the slew rate of the output signal to a second rate lower than the first rate. The output signal crosses the predefined threshold voltage in the second region. In a third region of the transition, the circuit can increase the slew rate of the output signal to a third rate greater than the second rate. The transition can complete in the third region. The circuit can output the output signal to drive a transistor in an output drive stage of the driver circuit.
