title = "Hum noise suppression using an on-chip N-path notch filter",
abstract = "This paper proposes an on-chip implementation of N-path notch filter for hum noise suppression. The suppression of hum noise frequency at 50 or 60 Hz requires a filter with a large time constant. The conventional N-path notch filter requires a total capacitance in the order of micro-Farads. A fully SC topology is utilized to reduce the total capacitance down to 213pF and thus enable an on-chip implementation of the filter. Simulation results show a hum noise suppression by 62.94dB with a filter notch bandwidth of 1.13Hz. The integrated output noise of the filter is 49.67µVrms.",
