Low Power ECG Processing ASIC

Abstract

We designed and evaluated ASICs (Application Specific Integrated Circuits) for the human activity monitoring systems to reduce the total power consumption. The ASIC extracts the heart rate from measured ECG (Electrocardiogram) raw signal. To realize the ASIC with ultra-low power consumption, we used novel algorithm based on fuzzy logic which is very simple and light processing. The fabricated ASIC shows sufficient function and low power as low as 2 µW.85% of the power consumption for MPU (Micro-Processing Unit) processing was cut by using the heart rate extraction ASIC.
