Abstract :
Charge-coupled-device (CCD) transversal filters are most commonly implemented using the split-electrode technique. Tap-weight accuracy is a major factor limiting the performance (stopband attenuation in particular) of these devices. In the letter an implementation technique is proposed which reduces this coefficient sensitivity and also offers other performance advantages.
