A high energy-efficiency capacitor switching scheme for successive approximation register (SAR) analogue-to-digital converters (ADCs) is presented. The switching method, verified on a 10-bit SAR scheme that uses bottom plate sampling, achieves an average switching energy and area reduction of 99.32 and 96.5%, respectively, with respect to the conventional solution.
