摘要

In this paper, a novel low-energy capacitor switching scheme for low power successive approximation register (SAR) analog to digital converter (ADC) is presented. The proposed scheme in this paper can achieve 99.9% savings in switching energy and 75% less number of capacitors compared to the conventional architecture. The proposed method is the most energy-efficient switching scheme among the reported switching techniques.
