  4. Abstract:
  5. A highly energy-efficient switching method for capacitor-splitting digital-to-analogue converter (DAC) in successive approximation register (SAR) analogue-to-digital converters (ADCs) is presented. In the proposed DAC, a bottom-plate sampling method is introduced which requires only one reference voltage (Vcm = 1/2Vref) during the entire DAC switching steps. Therefore, in addition to the switching energy reduction, the precision of the DAC is increased since only one reference voltage is used. The DAC average switching energy and the area are reduced by 98.44% and 50% compared with the conventional binary weighted DAC
