Abstract
Certain aspects of the present disclosure generally relate a dual feedback loop regulator. For example, the regulator may include a first amplifier having an output coupled to an output node of the regulator, the output node further coupled to a first feedback path and a second feedback path of the regulator. A first input of a second amplifier may be coupled to the first feedback path and a second input of the second amplifier may be coupled to a reference path. The regulator may also include a transconductance stage having a first transistor and a first current source, the first transistor and the current source coupled to the first feedback path and the second feedback path, and a transimpedance stage coupled to the transconductance stage and an input of the first amplifier.
