A ±6ms-accuracy, 0.68mm2, and 2.21 µW QRS detection ASIC

Abstract

Healthcare issues arose from population aging. Meanwhile, electrocardiogram (ECG) is a powerful measurement tool. The first step of ECG is to detect QRS complexes. A state-of-the-art QRS detection algorithm was modified and implemented to an application-specific integrated circuit (ASIC). By the dedicated architecture design, the novel ASIC is proposed with 0.68mm² core area and 2.21 µW power consumption. It is the smallest QRS detection ASIC based on 0.18 µm technology. In addition, the sensitivity is 95.65% and the positive prediction of the ASIC is 99.36% based on the MIT/BIH arrhythmia database certification.
