5. Dept. of Biomed. Eng.BME302: Medical InstrumentationKyung Hee Univ. 5 최법경 Bio-potential Amplifier Design Stray capacitance 부유 용량이라고도 하고 Parasitic capacitance( 기생 용량 ) 이라고도 한다. 이번 회로 디자인에서는 공기와 사람 사이 부유 용량이 문제가 된다. 그림과 같이 원래 보기에는 커페시터가 보이지 않지만 도선과 도선 사이에 자그마한 커페시터 가 존재하는 것 처럼 작동하는 것 그 커페시터를 부유용량이라고 한다.
