Abstract
In one embodiment the present invention includes a voltage regulator circuit comprising a voltage to current converter. The voltage to current converter is coupled to provide a current to maintain an output voltage under changing load conditions. A transconductance of the voltage to current converter is independent of the output current and therefore improves stability for the voltage regulator across load conditions.
