Classification: CPC H  G | IPC G  H

Claim 6:
7. A regulator system, comprising:
a plurality of detectors each comprising:
a current comparator configured to generate an output by comparing a reference voltage to a trigger voltage, wherein the trigger voltage is determined by one or more process variations of the current comparator; and
a compensation circuit comprising at least one compensation transistor configured to compensate for at least one process variations of the current comparator; and

a plurality of charge pumps each associated with at least one of the plurality of detectors, wherein each of the charge pumps is configured to generate a predetermined charge,
wherein the current comparator comprises:
a positive reference system including a PMOS current source and a PMOS pass-gate;
a negative reference system including an NMOS current source and an NMOS pass-gate; and
a transistor coupled between a pump output voltage input and at least one of the PMOS pass-gate and the NMOS pass-gate.
