Abstract
In certain aspects, a method for voltage regulation includes adjusting, using a feedback circuit, a resistance of a first pass element in a direction that reduces a difference between a reference voltage and a feedback voltage, wherein the first pass element is coupled between an input and an output of a voltage regulator, and the feedback voltage is equal to or proportional to a voltage at the output of the voltage regulator. The method also includes adjusting a bias voltage of the feedback circuit in a direction that reduces the difference between the reference voltage and the feedback voltage.
