Patent ID: 6911930

Claim:
A cell array having a plurality of cell elements integrated on a wafer in a bidimensional cell matrix, at least one integrated cell element exhibiting a mismatch between its actual physical property and a nominal property value, the mismatch of the at least one cell element being a function of the distance of the respective cell element to a center of the cell array having a bidimensional mismatch distribution, the plurality of cell elements arranged in rows and columns; wherein the cell elements are connected in series in a wiring pattern in which, for a plurality of rows of cell elements, each row of cell elements includes more than two series connections to cell elements of one or more other rows, and for a plurality of columns of cell elements, each column of cell elements includes more than two series connections to cell elements of one or more other columns; and wherein the cell matrix comprises a first number (N) of cell element rows and a second number (M) of cell element columns, and wherein the first number (N) of cell element rows is equal to the second number (M) of cell element columns.
