Le bourdonnement tel que l’interférence des lignes électriques est l’un des problèmes critiques de l’acquisition de signaux biomédicaux. Diverses techniques ont été proposées pour supprimer les interférences des lignes électriques. Cependant, certaines techniques nécessitent davantage de composants et de consommation d’énergie. La profondeur d'encoche dans les circuits de filtre coupe-bande à N chemins conventionnels nécessite un nombre plus élevé de chemins et coupe la résistance. Cela rend le filtre coupe-bande N-path conventionnel moins efficace pour supprimer le bourdonnement. Ce travail a proposé le nouveau filtre coupe-bande N-path pour la suppression du bourdonnement dans l'acquisition de signaux biomédicaux. Le nouveau filtre coupe-bande N-path atteint une profondeur de coupe supérieure à 40 dB avec une fréquence d'échantillonnage de 50 Hz et 60 Hz. Bien que les circuits proposés utilisent moins de chemins et coupent la résistance. Le circuit proposé a été vérifié à l'aide d'un signal ECG artificiel contaminé par un bourdonnement à la fréquence 50 Hz et 60 Hz. La sortie du filtre coupe-bande N-path permet d'obtenir un signal sans bruit même si la fréquence d'échantillonnage change.

Abstract: Hum noise such as power line interference is one of the critical problems in the biomedical signal acquisition. Various techniques have been proposed to suppress power line interference. However, some of the techniques require more components and power consumption. The notch depth in the conventional N-path notch filter circuits needs a higher number of paths and switches off-resistance. It makes the conventional N-path notch filter less of efficiency to suppress hum noise. This work proposed the new N-path notch filter to hum noise suppression in biomedical signal acquisition. The new N-path notch filter achieved notch depth above 40dB with sampling frequency 50Hz and 60Hz. Although the proposed circuits use less number of path and switches off-resistance. The proposed circuit has been verified using artificial ECG signal contaminated by hum noise at frequency 50Hz and 60Hz. The output of N-path notch filter achieved a noise-free signal even if the sampling frequency changes.
