  2. Bio potential amplifier design • 심전도의 측정 • 1. • 2. BW : 0.05 – 100Hz • 3. DC contact potential : 전극과 피부를 접촉하면서 발생 • 4. Contact impedance : • 전원 및 소자 • 1. ADC 입력범위 : • 2. 전원 : • 3. Opamp : 에서 saturation 이 두 신호의 크기는 작을수록 좋다. 2014.04.29

  3. Bio potential amplifier design 60Hz Power line LA - + RA RL 305mV 우리몸에 60Hz 신호가 흐르고 있으므로 60Hz의 전류와 전압이 잡음처럼 동작함 ⇒제거해야 하는 신호 300mV 2014.04.29
