(designed mdac structure and obtained residue chara for each stages..with and without redundancy)
Now i need to combine the bits
(adc out) of each stage to get the digital output .what technique should i use to obtain the output..i goggled about it and the result obtained was little bit confusing..
If each stage is for one of the bits in the output, then you just need to sum all of the stages' digital output bits, weighted by the correct power of two. You would multiply the output bit from each stage by 2 to the power that corresponds to the bit-position for that stage, and then sum that with the results from all of the other stages. I guess your MSB (most significant bit) comes from the first stage, and so on?
Don't you need a sample-and-hold just before the "+" summing input?
