Low-Power ECG Processing ASIC

SUMMARY We designed and evaluated ASICs (application‐specific integrated circuits) for a human activity monitoring system in order to reduce total power consumption. The ASIC extracts the HR from the measured electrocardiogram (ECG) raw signal. To create an ASIC with ultra‐low power consumption, we...

Description
Summary:SUMMARY We designed and evaluated ASICs (application‐specific integrated circuits) for a human activity monitoring system in order to reduce total power consumption. The ASIC extracts the HR from the measured electrocardiogram (ECG) raw signal. To create an ASIC with ultra‐low power consumption, we used a novel algorithm based on fuzzy logic that is very simple and requires minimal processing power. The fabricated ASIC shows sufficient functionality and a power level as low as 2 μW. A total of 85% of the power consumption in microprocessing unit (MPU) processing was cut by using the heart rate extraction ASIC.
