Abstract

본 발명은 지수함수 근사를 이용한 위상 정합 대역 통과 필터에 관한 것으로서, 기생저항을 포함하는 인덕터와 제1 증폭기가 피드백 연결되어 있는 제1 소자와 기생저항을 포함하는 커패시터와 제2 증폭기가 피드백 연결되어 있는 제2 소자를 포함하는 복수의 필터 소자들과 상기 복수의 필터 소자들을 연결하는 커플링 커패시터를 포함하며, 상기 제1 소자의 임피던스는 주파수와 증가 지수함수 관계에 있고, 상기 제2 소자의 임피던스는 상기 주파수와 감소 지수함수 관계에 있으며, 상기 제1 소자와 상기 제2 소자가 병렬로 연결되는 것을 특징으로 한다. 본 발명의 지수함수근사를 이용한 위상 정합 대역 통과 필터에 의하면 음저항을 이용하지 않고도 기존의 인덕터와 커패시터를 그대로 이용하여 고성능의 위상 정합 대역 통과 필터를 구현할 수 있다. 또한, 임피던스 특성이 주파수와의 지수함수에 근사하는 소자를 사용하므로 기존의 필터보다 주파수 선택도가 높게 되며, 이로 인해 채널 선택 필터와 같이 높은 큐값과 안정도를 요구하는 필터를 구현할 수 있다.
