A Study on the Graphical Representations of the 2-Port Parameter on the Load Plane by the Bilinear Transformation

쌍일차 변환에 의한 부하평면 2-포트 매개변수의 그래픽적 표현에 관한 연구

In this paper, graphical representations of parameter variations affected by series or parallel feedback in the load plane were studied. As a result of transformations, all parameters of 2-port was converted to circles, and the step of noise circles and gain circles was 0.1 dB and 1dB, respectively. Compared with conventional commercial CAD softwares, the circuit design procedures could be verified much more systemically. This CAD was programmed in C-language and executed in IBM-PC with VGA graphic adaptor.
