The weights of the individual data tap transistors 295 (and 297) may be incrementally related (i.e., EQW1=EQW2+K=EQW3+2K . . . , where K is a constant), exponentially related (i.e., EQW1=EQW2*K=EQW3*K2 . . . ) or may have any other desired relationship (including having the same weight values or including subsets of weight values that are the same).
