Abstract

The design of a low-pass elliptic filter basing on CSMC DPDM 0.6 mum CMOS model is presented. This filter can realize both low-pass and notch functions. The filter based on OTA-C structure is designed for the EEG detection. The simulation results based on the tool of Sprectre by Cadence Company show that the filter has desire pass-band and provides 58.5 dB attenuation for the 50 Hz power line interference. Therefore, the proposed filter structure has good performance.
