Proportional feedback for reduced overshoot and undershoot in a switched output
Abstract:
Embodiments of apparatuses and methods for proportional feedback for reduced overshoot and undershoot in a switched output are described. An embodiment of an apparatus includes a switching output stage configured to receive an input signal and provide a responsive output signal. The apparatus may also include a pulling circuit coupled to one of the first switching device and the second switching device. The pulling circuit may pull a control voltage of power transistors in the switching output stage to reduce impedance of at least one of the transistors in response to a determination that the output signal at the common output node is outside of a predetermined range of a threshold value. Pulling strength may increase as a voltage difference between the output signal and one of the first supply voltage and the second supply voltage increases.
