Abstract
Systems and methods are provided for monitoring a voltage. A level shifter is configured to generate a current proportional to the voltage of the battery cell. A delta-sigma modulator is configured to convert the current into a first density modulated bitstream representing the voltage of the battery cell. A first reference source is configured to provide a second density modulated bitstream representing a first threshold voltage. A first comparator is configured to compare the first density modulated bitstream and the second density modulated bitstream.
