要約(英語): A wearable fetal heart rate measuring device is desired for the early detection of the abnormal development of a fetus. A low noise amplifier which occupies small chip area is indispensable for implementation of the wearable measurement device because a multi-point measurement is necessary for accurate measurement using an independent component analysis. In this paper we propose a novel multi-channel amplifier for biomedical applications. A reference input terminal of the proposed amplifier is shared by plural sub-amplifiers to reduce the power consumption. Hspice simulations show that the power consumption of the proposed circuit with 4 inputs is 39% lower than that of a conventional amplifier. It is shown that an independent component analysis based on Fast ICA can extract a fetal electrocardiogram from the output voltages of the proposed amplifier.
