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 8):
The startup circuit of  claim 1 , wherein when a power supply voltage is applied to the power supply voltage terminal, a voltage difference between the first current electrode and the control electrode of the second transistor is substantially zero volts.
