摘要：
An energy-efficient switching scheme with common-mode voltage variation in 1LSB for successive approximation register analogue-to-digital converters is proposed. Based on the two-step architecture, spilt-capacitor method and reusing of the unit capacitor technique, the proposed switching scheme achieves 99.35 % less switching energy and 73.4 % less number of capacitors over the conventional architecture with common-mode voltage variation in 1LSB.
