Abstract:
In accordance with embodiments of the present disclosure, an apparatus may include an input for indicating a characteristic of an output load current of a switched output stage comprising at least one driver device and a predriver circuit coupled to the input and a gate terminal of the at least one driver device, the predriver circuit for driving an input voltage signal to the gate terminal and configured to select an effective impedance of the gate terminal based on the input for indicating the output load current. In accordance with these and other embodiments of the disclosure, a method may include receiving an input for indicating a characteristic of an output load current of a switched output stage comprising at least one driver device and selecting an effective impedance of a gate terminal of the at least one driver device based on the input for indicating the output load current.
