Abstract: A multi-stage, low-offset, fast-recovery, comparator system and method for: reducing the input offset voltage of the zeroing amplifier by a factor essentially equal to gain of the zeroing amplifier; reducing the input offset voltage of the combined main and zeroing amplifiers by a factor essentially equal to the product of the gains of the main and zeroing amplifiers; and amplifying the input signal to the amplification stage in accordance with the gain of the main amplifier to generate an amplified high-resolution signal.
