CGIC의 디지탈 구조 및 잡음특성

Digital Configuration and Noise Characteristic of CGIC

포트 콘덕턴스가 서로 독립적인 CGIC의 디지탈 구조를 APF를 이용하여 네 종류로 구분하여 실현하였다. 포트 콘덕턴스에 의해서 결정되는 곱셈계수의 양자화 과정에서 발생되는 출력잡음식을 유도하여 해석함으로써 각각의 성능을 비교하여 적용방법을 설명하였다.

Making use of APF(All Pass Filter), four kinds of digital CGIC(Current-coversion Generalized Immittance Coverter) configurations have been realized, which have independent port conductances respectively. By according to hardware requirements and quantization noises generated at CGIC output due to the roundoff of the multiplier, thier performances have been compared with one another and their application method is illustrated.
