This paper describes a low-power 25-kS/s successive approximation register (SAR) analog-to-digital converter (ADC) for biomedical applications. The ADC employs a novel low-energy and area-efficient tri-level switching scheme in the DAC. Compared to the conventional SAR ADC, the average switching ene...
