Abstract :
An area efficient scheme for WCDAC (Weighted Capacitor Digital-to-Analog Converter) is proposed. This new architecture adopts an extensive charge-sharing scheme to enhance the overall converting resolution without additional increase of the capacitor distribution ratio. The validity of the approach is clearly proved by the analytic method and simulations.
