Hum noise activity such as power line noise is one of critical problems in biomedical signals processing. Various approaches both analog or digital techniques have been proposed. However, these approaches have some disadvantages. This paper proposes the N-path notch filter as a hum noise suppression. The notch depth in a conventional N-path notch filter depends on the value of off-resistance in the switch. A new N-path notch filter with additional sample-and-hold (S/H) and leak buffer circuit is proposed. Measurement results show with the additional leak buffer circuit improves the notch depth by 61.25dB.
