Abstract

In this paper, the filter design and simulation are performed to construct the multi-channel cardiac activation main amplifier. The main amplifier consists of sample and holder, variable high pass filter, notch filter, variable low pass filter. The general 64 channel configuration is expanded into 128 channels to enhance the spatial resolution and the filter is designed for 128 channels cardiac activation main amplifier.

본 논문에서는 다중 채널 심장 전기도 주 증폭기의 중요한 부분인 필터를 설계하고 시뮬레이션을 통하여 성능을 분석하였다. 주 증폭기는 샘플/홀더, 가변 고역통과 필터, 노치 필터, 가변 저역통과 필터로 구성된다. 필터는 기존의 64 채널의 공간 분해능을 향상시키기 위하여 128채널을 고려하여 설계되었다.
