MATLAB 中的 (pseudo) random number generator
一般都假設 statistics of mismatch of unit cells (in DAC) follows Gaussian distribution
In addition to that,
Process gradient (along the X-coordiate, and/or along the Y-coordiate) can be modeled by percentage increment with index i and index j.
"i" represents the position in the cell array along the X direction.
"j" represents the position in the cell array along the Y direction.
% iArray(i, j) = sqrt(dX^2 * (i-1)^2 + dY^2 * (j-1)^2) + 1; |
