Abstract

Embodiments described herein provide a voltage regulator that includes an error amplifier configured to provide a difference signal indicative of a voltage difference between a reference signal and a feedback signal, a pulse width modulation generator configured to receive the difference signal and to output a pulse width modulated signal based on the difference signal, and one or more transistors configured to receive the pulse width modulated signal at a gate of the one or more transistors, and to provide the feedback signal at a drain of the one or more transistors as a regulated voltage that is adjusted to match the reference signal so as to reduce the voltage difference between the reference signal and the feedback signal.
