Abstract
Methods and systems to generate a digital error indication of an input signal relative to a reference signal, using resistors, comparators, and latches. The digital error indication may indicate that the input signal is within a range of the reference signal, above the range, or below the range. The methods and systems may be implemented within a multi-phase digital voltage regulator to generate a digital error indication for each of a plurality of phase currents relative to an instantaneous average of the phase currents. The digital voltage regulator may be fabricated on an integrated circuit die with a corresponding load, such as a processor. The digital voltage regulator may include a plurality of multiplier or look-up based gain modules, each to receive a corresponding one of the digital error signals and to output one of three values. Outputs of each gain module may be integrated over time.
