Abstract:
Embodiments may include a method, system and apparatus for providing a reference voltage supply. A series resistor is provided between a power supply and a bandgap circuit coupled to an amplifier. A shunt transistor circuit is operatively coupled to the series resistor. A programmable output voltage is provided based upon the shunt transistor circuit and a first value of the series resistor.
