Abstract
A transversal filter of the split electrode type employing a bucket-brigade device (BBD) is described. The BBD wells extend beyond the edges of the clocked gates of the BBD below second gates of different areas. These mask programmed second gates provide the filter output. Unlike other split electrode, capacitance sensing filters, these gates are not clocked, thus the filter has simplified output circuitry and a greater dynamic range.
