Method for reducing coefficient sensitivity in lowpass CCD transversal filters
Navin K. Kapur, Spandan Roy · Electronics Letters · 1981
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.
