A state-of-the-art energy-efficient switching scheme for successive approximation register (SAR) analogue-to-digital converter (ADC) is proposed in this letter. With this proposed switching scheme, the average switching energy can be reduced by 98.8% compared to the conventional approach, and 75% of the chip area can be saved. While combining with an integer-based split-capacitor structure, both the average switching energy and chip area can be approximately reduced further by half. Yet,
