1. A voltage regulator circuit comprising:
a negative-channel metal-oxide semiconductor (NMOS) coupled to a regulated voltage output of the voltage regulator circuit;
a sensing circuit for sensing the regulated voltage output;
a reference voltage circuit for supplying a correct bias voltage to the sensing circuit; and
a voltage inversion circuit coupled between the sensing circuit and the NMOS, wherein the voltage inversion circuit lacks a resistor.
