Abstract
A power switch includes a control circuit, a cross-coupled amplifier, a first switching circuit coupled between a first output terminal and the first controlled ground terminal, and a second switching circuit coupled between a second output terminal and the second controlled ground terminal. The control circuit is configured to connect the second controlled ground terminal to a ground during a first period that a voltage level at the first output terminal is switched from the ground to a first voltage level and to set the second controlled ground terminal at an elevated ground level during a second period that the voltage level at the first output terminal remains at the first voltage level.
