ABSTRACT:
By dividing the split gate electrode into four sections, in which two non-adjacent sections are solely clock sections and the other two sections are "plus" and "minus" sections, respectively, and in which the sum of the lengths of the first two sections, in serial order, is substantially equal to the sum of the last two sections, in serial order, only a single mask must be changed, in the fabrication of transversal filters that exhibit a small common mode, in order to change the particular filter characteristic of a fabricated filter.
