Realization of Multi-Channel Active Filters by Using Operational Amplifiers

연산 증폭기를 사용한 다중 챈넬능동휠타의 구현

This paper presents a synthesis procedure of multi-channel active filters, which realizes an arbitrary N*N matrix of real rational functions in the complex variable s as a voltage transfer matrix. The resultant network reveals a transformerless grounded active RC(2N+1)-terminal network. The active network is consisted of six 2N-port RC networks with 2N single-ended operational amplifiers.
