Abstract

A voltage regulator includes a regulator input connected to a reference voltage; a regulator output that outputs a regulated voltage to an electrical load; a first loop, the first loop configured to receive the reference voltage, the first loop outputting a bias voltage; a second loop, the second loop configured to receive the bias voltage as an input; and a bias voltage capacitor connected to a node between the first loop and the second loop.
