Abstract:
In an embodiment, a digital output driver circuit comprises an output stage having first and second transistors. A drive stage is configured to drive control terminals of the first and second transistors and comprising switching circuitry and current generator circuitry. In a first configuration, the driver circuit is configured to connect a control terminal of the second transistor to the reference node to turn off the second transistor; and connect a first capacitance to the current generator circuitry and to a control terminal of the first transistor to turn on the first transistor. In a second configuration, the driver circuit is configured to turn off the first transistor and connect the control terminal of the second transistor to the current generator circuitry and to the second capacitance to turn on the second transistor.
