Hello, In the attached article shown bellow we have 2.5 bit ADC we have the 0.5Vref area between -7/8 and 7/8 Vref.
we cannot expand more the 0.5Vref area because we make jumps every 2/8 ,so 7/8 is the maximal availbale.
But In 1.5 ADC its between -1/4 and 1/4 akthough we can make it -3/4 -1/4 1/4 3/4.
What is the effect f the redundant area for 2.5bit.
why making it wider makes itmore accurate.
Il be glad to have some numerical example.
