Abstract
Systems and methods providing for improved voltage regulation of a supply voltage for an integrated circuit are described herein. The voltage regulator circuit includes a feedback circuit coupled to a first current path and adapted to maintain a gate voltage of a feedback transistor substantially constant. A pass device is coupled to a second current path and adapted to receive a signal with a magnitude based on first and second currents supplied by first and second current sources to the second current path. In an embodiment, the first current is a substantially constant current and the second current has a magnitude based on a magnitude of the voltage at the feedback transistor gate and a magnitude of a voltage at an output of the voltage regulator circuit coupled to the pass device.
