- 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. - Keywords:
- Analogue-to-Digital converter, dithering, large scale errors
