Abstract:
Methods and apparatus to reduce voltage bounces and spike voltages in switching amplifiers are disclosed. An example apparatus to reduce spike voltages in a switching amplifier disclosed herein comprises an input to sense an output voltage of the switching amplifier, and a pull-down circuit to electrically couple the apparatus with a transistor in the switching amplifier, wherein the pull-down circuit is configured to vary in strength based on the output voltage sensed by the input.
