NDLI: Low power DAC with single capacitor sampling method for SAR ADCs

Content Provider	IET Digital Library
Author	Yazdani, B. Khorami, A. Sharifkhani, M.
Abstract	An ultra-efficient switching method for successive approximation register ADCs is proposed. In this method, the input signals are sampled in a special fashion to reduce the switching energy. Owing to the sampling method, only one reference voltage (V q = V ref/4) is required to implement the switching steps. Therefore, in addition to reduction in the switching energy (due to the lower supply voltage), the precision of the DAC is improved. The proposed method reduces the switching energy and area by 99.41 and 50%, respectively, compared with the conventional method.
