Abstract
Official abstract text for this publication.
A linear regulator and a method of regulating a supply voltage are provided. Embodiments include a linear regulator with a first feedback loop and a second feedback loop. The first feedback loop is characterized by a first bandwidth and a first gain. The first feedback loop includes a first amplifier characterized by an output impedance which is significantly reduced in order to maximize the bandwidth of the first feedback loop when driving the capacitance of a control input of a series pass element. The second feedback loop is characterized by a second bandwidth and a second gain. The second feedback loop includes a second amplifier that controls the current in the first amplifier in the first feedback loop.
