Abstract

This paper presents the first fully integrated sub-1V 3-lead wireless ECG System-on-Chip (SoC) for wireless body sensor network applications. The SoC includes an ECG front-end, a driver-right-leg circuit, a custom designed MCU, two banks of 16kb SRAM, and a MICS band transceiver. The measurement results show the SoC consumes 17.4μ and 74.8μW, respectively, in heart rate detection and raw data acquisition modes under sampling rate of 500Hz. This makes it one of the best ECG SoCs among state-of-the-art biomedical chips.
