Regulated voltage systems and methods using intrinsically varied process characteristics

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 compensation circuit includes at least one compensation transistor configured to compensate for variations in a constant transconductance bias current of the comparator.
