Low Power ECG Processing ASIC

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.
