Abstract
Official abstract text for this publication.
The voltage regulator device has a wide band amplifier having an input reference voltage, Vref and an input feedback voltage, Vfbk. The device has a source follower coupled to the wide band amplifier, the source follower coupled to an output of the wide band amplifier. The device has a VDD source, a regulator output, and a current source coupled to the source follower and the VDD source. The device has a low frequency path comprising a first transistor. The first transistor has a first gate, a first source, and a first drain. The first source is coupled to the VDD source. The first gate is coupled to a slow node, and the first drain is coupled to the regulator output. The low frequency path comprises a RC network, which has a capacitor, a resistor, and the slow node configured between the resistor and the capacitor. The device has a high frequency path comprising a second transistor. The second transistor has a second gate, a second source, and a second drain. The second source is coupled to the VDD source. The second gate is coupled to a fast node, and the second drain is coupled to the regulator output.
