Abstract: The indirect-contact ECG (IDC-ECG) shows large background noise in comparison with conventional ECG measurement. To improve the signal quality, close study of the background noise is necessary. This study was carried out to investigate how much the thermal noise influences the background noise in IDC-ECG. To do so, the thermal noise model was built for the active electrode. And then, the parameters which determine the thermal noise were estimated by measuring the gain of the active electrode. Finally, the level of thermal noise was estimated and compared with actual background noise. The results show that the thermal noise is the dominant component of background noise and the intrinsic noise of the preamp’s active devices is negligible.
