Classification: CPC G | IPC G

Claim 11:
12. The integrated circuit die of claim 6, further comprising:
wherein the second transistor has a control terminal coupled to receive the output voltage from the comparator of the voltage regulator, and has a first conduction terminal at which the copy voltage is generated based upon the difference between the variable current and the replica of the constant current;
wherein the second transistor is a replica of the first transistor;
a variable current source coupled to the first conduction terminal of the second transistor and configured to generate the variable current in response to a control signal;
an analog to digital conversion circuit configured to digitize the gate voltage and the copy voltage, compare the gate voltage to the copy voltage after digitization, to generate the leakage detection signal as asserted in response to the copy voltage being less than the gate voltage, and to generate the leakage detection signal as deasserted in response to the copy voltage being greater than the gate voltage; and
a control circuit configured to generate the control signal, and to increment the control signal in response to the leakage detection signal being asserted.
