Abstract
We report an asynchronous wake-up circuit with pattern recognition capabilities to duty-cycle biomedical system-on-chips in internet-of-things healthcare applications. The wake-up circuit is based on a level-crossing analog-to-digital converter to reduce both the number of samples and processing power. On-chip voltage references lower the overall system power consumption and reduce the number of external components. The circuit is highly configurable and can be used for a wide variety of applications. A 130 nm CMOS prototype is demonstrated with pathological electrocardiogram with premature ventricular contractions, reaching 74.8% of accuracy with only 2.1 μW at 1V supply.
