Abstract: We present a low power electrocardiogram (ECG) acquisition system with 28mW total power dissipation in this paper, which is almost half of traditional implementation below our measurements. The majority of this power reduction is due to use a fully integrated analog front-end (AFE) with inherent all the necessary functions that needed in traditional ECG acquisition implementation. This AFE is implemented in 0.18um CMOS technology, consumes only around 0.3mW. Therefore, our acquisition system is well suited for portable medical applications.
