A novel switching scheme for successive approximation register (SAR) analog-to-digital converter (ADC) is presented in this paper. Based on the asymmetric capacitor array and splitted MSB capacitor, the proposed scheme achieves 99.09% and 93.41% reductions in the average switching energy and capacitor area, respectively, over the conventional scheme. Moreover, the proposed SAR ADC obtains a moderate linearity performance with max(INL-RMS) less than 0.112 LSB, max(DNL-RMS) less than 0.160 LSB and consumes zero reset energy.
