Regulated voltage systems and methods using intrinsically varied process characteristics

摘要

A regulator system includes a multi-bit detector system and a multi-cell charge/discharge circuit. The multi-bit detector system includes a plurality of detectors. Each of the plurality of detectors has a predetermined threshold voltage. The multi-cell charge/discharge circuit includes a plurality of charge pumps. Each of the charge pumps is configured to generate a predetermined charge. Each of the charge pumps is associated with a predetermined threshold voltage of the detector circuit.
