An energy-efficient switching method for successive approximation register analog to digital converter is presented in this letter. The proposed two-step switching scheme using the goblet architecture achieves 99.52% less switching energy and 21.09% area reduction over the conventional switching scheme. Moreover, owing to the application of the goblet architecture, the proposed scheme employs only two reference voltages without any requirements for stability or accuracy of the third voltage level.
