Abstract:
A startup circuit for a voltage reference circuit is provided. The startup circuit includes first, second, and third transistors. The first transistor has a first current electrode coupled to the voltage reference circuit, a control electrode, and a second current electrode coupled to a ground terminal. The second transistor has a first current electrode and a control electrode both coupled to a power supply voltage terminal, and a second current electrode. The third transistor has a first current electrode coupled to the second current electrode of the second transistor and to the control electrode of the first transistor, a control electrode coupled to the voltage reference circuit, and a second current electrode coupled to the ground terminal. During application of a power supply voltage, the second transistor is off, thus providing only a leakage current to the gate of the first transistor. This provides for reliable startup with very low residual current after startup is complete.

Claim (Index 13):
The circuit of  claim 10 , wherein the voltage reference circuit comprises a current mirror, and wherein the drain of the first N-channel transistor is coupled to the current mirror to ensure that the current mirror is biased into conduction during the application of the power supply voltage to the power supply voltage terminal.
