Double-split-electrode transversal filter

Signal-Processing Applications of Charge-Coupled Devices

“…However, one could cascade several filters to obtain the desired attenuation. In particular to reduce the effect of the DCI noise, a new "double-split electrode" structure has been fabricated (Foxall et al 1977) which provides improved filter performance over the (a) (b) signal-split approach by reducing the common mode signal and noise pick up (Fig. 11 b).…”
