Abstract

A simulated floating inductor using two fully-differential OTA's and a capacitor is presented. The theory of operation is described and experimental results are used to verify theoretical predictions. The results show close agreement between predicted behavior and experimental performance. The proposed floating inductor has about two times higher Q factor than conventional designs. The application of the inductor to a ladder type third order ellitic low pass filer is also presented.

두 개의 완전-차동형 OTA들과 하나의 커패시터를 이용한 시뮬레이티드 플로팅 인덕터를 제안했다. 제안한 플로팅 인덕터의 동작 원리를 기술했고, 실험 결과들을 제시했다. 실험 결과들은 이론적인 예측과 실험적인 성능이 잘 일치한다는 것을 보였고, 제안한 플로팅 인덕터가 기존의 인덕터들보다 약 두 배 큰 Q 인수를 가진다는 것을 보였다. 제안한 인덕터의 3차 일립틱 저역-통과 여파기에 응용 역시 제시하였다.
