표면 근전도 획득을 위한 휴대형 Analog front end 보드 설계

초록

High interests about a health , well-being and machines that can be controlled by user's will make a needs about accurate measurement to acquire the bio signals. In many kind of bio signals, surface EMG signal that generated by muscles is useful and important to analyze the wills of user accurately. But surface EMG signal has lots of noises and voltage level of signal is very low, so it is very hard to get a pure signal. Because of this, surface EMG signal acquisition board is very complex and hard to miniaturize. In same way, power consumption of the circuit is very high. In this paper, propose that roburst to noise and can process the four channel signal at the same time and low power and compact surface EMG signal acquisition board.
