Design and Analysis of An Active Comb Filter based on Low Transconductance OTA-C for Biomedical Applications

Arvind Kumar Sahu, Anil Kumar Sahu

Abstract: The design of a OTA-C based comb filter is presented in this paper. The comb filter is designed by using only OTA and capacitors, which can be easily fabricated into an IC. The filter was implemented in Tanner EDA tool using 250nm technology. The simulation result shows that this filter was able to provide stop band attenuation of 20db for 50 Hz, 150 Hz and 250 Hz powerline harmonics.

Keywords: Biomedical signal, Comb filter, OTA-C, powerline interference
