WebThis paper provides detailed mathematical analysis that investigate the effect of charge-sharing between an analog-to-digital converter (ADC) reference decoupling capacitor and a charge-redistribution based differential split-monotonic capacitive digital-to-analog converter (CDAC).
WebJul 28, 2024 · Capacitor plates that are parallel and of the same size will have equal and opposite charge. But for there to be unequal charge on two capacitor plates there needs to be a difference in the plate areas and, … WebThe redistribution of charge in capacitor occurs when two capacitors are connected by a wire. After the redistribution of charges, the new charge on the second capacitor Q ’ 2 …
