An Active Bandpass Filter Using Negative Resistance Circiuts
부성저항을 이용한 능동 대역 통과 여파기
Abstract
In this study, An active band grass filter for 2.14GHz have been designed with MMIC using negative resistance circuit. The negative resistance element was realized with a common-drain FET with series inductive feedback. The designed active filter showed an insertion loss of 0dB at 2.14GHz and a 3-dB bandwidth of 125MHz.
