N2 - Recently, a novel recording system is strongly required for agile and precise recording of biosignals in various fields, such as medicine, neuroscience, BMI (Brain Machine Interface), and so on. To enable such various biosignal recording, we have proposed an agile biosignal recording system with a newly designed analog front-end LSI chip having amplification, filtering, and A/D conversion functions. In this paper, we designed and evaluated a neural signal recording circuit and a portable front-end motherboard. The neural signal recording circuit chip and discrete ICs were mounted on the motherboard. We confirmed that our functional LNA (Low Noise Amplifier) had variable gains and cutoff frequencies appropriate for various biosignals, and also confirmed that biosignal recording board system successfully measured a human electrocardiogram.
