A Study on the Realization of 3rd Order active Low-pass Filter using Switched-Capacitor
Switched-Capacitor를 이용한 3차 지향통과능동 여파기의 실현에 관한 연구
Abstract
In order to realize the simple and economic 3rd order LPF using switched-capacitor(SC), we proposed the 3rd order RC LPF using a OP amplifier and realized the 3rd order SC LPF by replacing all the resistors in the RC LPF to SC. The frequency response of SC LPF was compared with the that of RC LPF. As a result, it was found that the response of realized SC LPF is almost similar to that of RC LPF.
