Abstract
Official abstract text for this publication.
An electronic device includes a power supply, a ground, and an intermediate ground having a voltage less than a voltage of the power supply and greater than a voltage of the ground. The electronic device also includes an error amplifier having an input stage coupled between the power supply and the ground, and an output stage coupled between the power supply and the intermediate ground. A ballast transistor is coupled to receive an output from the error amplifier. A feedback circuit is coupled to an output of the ballast transistor to generate feedback signals, and the error amplifier operates in response to the feedback signals.
