Abstract:This research article presents the systematic development of a current-mode-based active comb filter designed to mitigate the undesirable PLI (power line interference) and its harmonics contaminating biomedical signals. The filter is designed using the latest currentmode Analog Building Block (ABB), specifically Voltage Differencing Gain Amplifiers (VDGA). This filter effectively suppresses the 50Hz PLI and reduces the odd consecutive harmonics of the 50Hz PLI, including the third harmonic at 150Hz, the fifth … Show more
