LARGE SCALE ERROR REDUCTION IN DITHERED ADC

J. Holub, O. Aumala
  • Abstract:
    The combination of dithering and correcting table is the way of improvement not only of ADC resolution but also of linearity - effective number of bits. Dithering is used to reduce small-scale errors, such as quantization error, while correcting table reduces large-scale errors.
    The contribution describes design and practical experience with ADC unit based on single-chip micro-controller 80C552 that uses above described correction procedure. Sub-quantum accuracy has been achieved.
