I am designing a 8 bit sar adc with a single comparator. I have following questions :
1 . is the comparator offset an issue?
2. what is the maximum comparator offset value that can be tolerated for a sar adc?
3.if the comparator offset needs to be canceld what canselation technics can be used?
2. what is the maximum comparator offset value that can be tolerated for a sar adc? beyond +/- 2.5V. if the offset uf beyond its reference point, the ADC will not recognize whether it is a MARK or SPACE (1/0).
3.if the comparator offset needs to be canceld what canselation technics can be used? always set your comparator to 0 LEVEL, meaning add a reference point.
