Description: 
A new approach to the design of a comb filter using current conveyor is proposed to eliminate the undesired harmonic interference from biomedical signal. In this approach, a number of inverted band pass filters are used to construct a comb filter. The components used are second generation current conveyor (CCII), capacitor and resistor. To verify the performance of the proposed circuit, the comb filter is designed to eliminate the unwanted power line frequency of 60 Hz and its odd harmonics such as 180, 300 and 420 Hz. The proposed circuit is simulated by implementing CCII±using a macro model of commercially available CFOA IC AD844 as well as 0.18 μ m CMOS technology. The circuit is also verified experimentally by using commercially available IC AD844. The effectiveness of harmonic removal has also been tested.
