Abstract:
A start-up circuit for a bandgap reference voltage generator circuit, including a first native transistor with a drain connected to a supply voltage of the bandgap reference voltage generator circuit and a source connected to a gate of the first native transistor; a low voltage transistor with a source connected to ground, a drain connected to the source of the first native transistor, and a gate connected to a resistor; a second native transistor with a source connected to the resistor, a gate connected to the source of the first native transistor; a high voltage transistor with a drain connected to a drain of the second native transistor and a source connected to the supply voltage; and a transistor with a gate connected to the gate of the first high voltage transistor and a drain which provides a start-up current for the bandgap reference voltage generator circuit.

Claim (Index 1):
A start-up circuit for a bandgap reference voltage generator circuit, comprising:\n a first transistor ( 504 ) of a first type with a drain connected to a supply voltage of the bandgap reference voltage generator circuit and a source connected to its own gate, in which the first transistor has a threshold voltage less than approximately 0.5v; a second transistor ( 602 ) of the first type with a drain connected to the source of the first transistor and a gate coupled to a voltage reference resistor (R 6 ), the second transistor having a gate oxide thickness approximately the same thickness as the first transistor; a third transistor ( 506 ) having a source connected to the voltage reference resistor (R 6 ), and a gate connected to a node between the first transistor ( 504 ) and second transistor ( 602 ), in which the third transistor has a threshold voltage less than approximately 0.5v, wherein raising the supply voltage of the bandgap reference voltage generator causes an electric current to flow through the reference resistor that is related to a voltage flowing through across the reference resistor; and a current mirror structured to duplicate the electric current flowing through the reference resistor as a startup current for the start-up circuit.
