This paper proposes a power and area efficient electrocardiogram (ECG) signal processing application specific integrated circuits (ASIC) for wireless body area networks (WBAN). This signal processing ASIC can accurately detect the QRS peak with high frequency noise suppression. The proposed ECG signal processor is implemented in 0.18μm CMOS technology. It occupies only 1.2mm2 in area and 9μW in power consumption. Therefore, this ECG processor is convenient for long-term monitoring of cardio-vascular condition of patients, and is very suitable for on-body WBAN applications.
