A resolution-reconfigurable 5-to-10b 0.4-to-1V power scalable SAR ADC

Applications such as sensor networks and medical monitoring often require ADCs that can digitize signals with varying bandwidth and dynamic range requirements. In energy-constrained systems, it is beneficial to adapt the ADC performance to the signal to avoid consuming power on unnecessary bandwidth or accuracy. Therefore, this paper presents a single reconfigurable SAR ADC whose power scales with resolution and sample rate to improve energy efficiency, while reducing system complexity and cost.
