Classification: CPC G  H | IPC G  H

Claim 0:
1. A voltage supervisor comprising:
a first transistor coupled between a first supply voltage and a second supply voltage;
a second transistor coupled between the first supply voltage and the second supply voltage;
and the voltage supervisor configured to:
provide a first current proportional to a difference in gate-to-source voltages of the first transistor and the second transistor;
provide a second current proportional to a difference in the first supply voltage and the difference in gate-to-source voltages of the first transistor and the second transistor;
compare the first current to the second current to determine a voltage value that changes a state responsive to the first supply voltage crossing a threshold; and
clamp the second current responsive to the first supply voltage crossing the threshold.
