发明名称 Methods and apparatus to reduce substrate voltage bounces and spike voltages in switching amplifiers
摘要 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.
