ECAP에 의한 Gyrator특성해석과 개선

Analysis and Improvement of Gyrator Characteristics by ECAP

능동 filter에 쓰에는 Gyrator를 구성하여 그 특성을 ECAP(Electronic Circuit Analysis Program)로써 해석하였고 그 결과로 나타난 문제점을 해결하고 특성을 개선하기 위한 조치로서 Colletor 측의 저항을 높이기 위하여 정전류전원회로를 이용하여 전원전압을 줄이고 ECAP로써 해석하여 그 조치가 정당함을 확인하였다.

ECAP(Electronic Circuit Analysis Program) is used for analysis of a gyrator network obtained by conventional approach. Thus obtained characteristics of the original network showed the necessity of some improvement. Modification of the network was made through DC Analysis of ECAP for improved behavior of gyrator. by the replacement of resistors in collector circuits with constant current source circuits, thus decreasing the required voltage of collector bias source voltage, and in turn, increasing collector resistances. The modified network was again analized through ECAP AC Analysis. The result justifies the modification of networks and tile utilization of a computer program for network analysis instead of a "breadboard" experiment.xperiment.
