I have the following questions about this paper:
(1)why will the residue error be reduced by a factor of 2 in X and Y direction when using common centroid switching?
(2)why will the residue error be reduced by a factor of 4 in X and 8 in Y direction when using Q2 random walk switching?
The following picture is got by matalb but I don't think it is right when considering the above two questions.Anyone can help me?

I am also designing my DAC according to this paper.
my question is about the decoding logic, i am not clear how the paper implement the logic. And i think the conventional row-col decoder can do this job better.
Since all of us are interested in the same paper, maybe we can form a small team to discuss about it.

" A 12-bit intrinic accuracy high-speed cmos dac" has four row-col decoder(8×8).
I tried to use logics to generate a big row-col decoder(16×16).
But I think if your dac is high speed, this one is difficult.
And I think this paper maybe use verilog or other tools.
I don't know if my mind is correct. I think your idea is good. Maybe we can form a small team to discuss about it .
