A novel energy‐efficient V CM ‐based monotonic capacitor switching scheme for successive approximation register (SAR) analogue to‐digital converters (ADCs) is proposed. Based on the third reference voltage V CM and monotonic capacitor switching procedure, the proposed switching scheme achieves 97.66% less switching energy and 75% less number of capacitors over the conventional architecture, resulting in the most energy‐efficient switching scheme among the reported switching sequences.
