/diy/ - Do It Yourself

Would this work as an ADC?
What am I overlooking?

>check if positive or negative
>amplifies previous signal by 2 and recenters it in the direction opposite the previously obtained bit
>repeats as many times as these are chained together

>muh bifurcation
>muh tail recursion
>muh one comparator per desired bit as opposed to the {2^n}-1 of a normal flash adc

Resistor ratios on the doubling amps would have to be pretty exact.
And the rails on the doubling amps and summing buffers would have to be twice as big as everything else.
One major issue with the amplification would be noise - But that might actually just end up working beautifully as natural dither.

Idk.
Am I crazy brilliant, or just crazy retarded?
