Abstract :
A novel sequential inter-stage correlated double sampling technique has been proposed. This technique provides considerable enhancement in the effective accuracy of a switched-capacitor architecture. Superior accuracy and thermal noise performance is achieved compared to the conventional correlated double sampling technique. The proposed approach provides higher input signal bandwidth by reducing the number of clock phases using a predictive phase compared to the other sequential techniques to achieve the same performance. Also, the proposed approach has the capability of driving both resistive and capacitive loads.
