Abstract: A stage, suitable for use in and analog to digital converter or a digital to analog converter, comprises a plurality of slices. The slices can be operated together to form a composite output having reduced thermal noise, while each slice on its own has sufficiently small capacitance to respond quickly to changes in digital codes applied to the slice. This allows a fast conversion to be achieved without loss of noise performance. The slices can be sub-divided to reduce scaling mismatch between the most significant bit and the least significant bit. A shuffling scheme is implemented that allows shuffling to occur between the sub-sections of the slices without needing to implement a massively complex shuffler.
